The value of pi is about 3.14, and it is the same when using both the area and circumference.
How to calculate circumference?The circumference is given by:
Circumference = π * diameter
For circle A:
25.12 = π * 8
π = 3.14
For circle B:
9.42 = π * 3
π = 3.14
The area is :
Area = π * diameter² / 4
For circle A:
50.24 = π * (8²)/4
π = 3.14
For circle B:
7.065 = π * (3²)/4
π = 3.14
The value of pi is about 3.14, and it is the same when using both the area and circumference.

What is 8 inches converted to feet? Write your answer as a fraction in simplest form
Answer: 2/3 feet
Step-by-step explanation:
Since there are 12 inches in a foot, 8 inches would be equal to 8/12 of a foot. We can divide the numerator and the denominator by 4.
8/12 = 2/3 feet
Answer:
2/3 feet
Step-by-step explanation:
How do we convert inches to feet?
To convert a number of inches into feet, we divide the number of inches by 12.Solving
8 ÷ 12 = 8/128 and 12 have a GCF of 4.8/4= 2, 12/4 = 32/3Therefore, the answer is 2/3 feet.

The vertical height in feet of a projectile on a planet in our solar system at a given time t in seconds is represented by the function h (t) = -4^2 + 24t Re-write h(t) in the form h(t) = a(t – h)^2 + k and determine the maximum height of the projectile. Show all work.
h (t) = -4t^2 + 24t = -4 (t² - 6t)
= -4 [(t - 3)² - 3²]
= -4 (t - 3)² + 36
max (3 ; 36)
(t - 3)² = t² - 2*t*3 + 3² = t² - 6t + 9
so it's why t² - 6t = (t - 3)² - 9
The maximum height of the projectile is 36 feet.
It is given that the projectile on a planet in our solar system at a given time t in seconds is represented by the function:
[tex]\rm h(t) = -4t^2+24t[/tex] can be written as a function:
[tex]\rm h(t) = a(t-h)^2+k\\[/tex]
It is required to determine the maximum height of the projectile.
What are maxima and minima?Maxima and minima of a function are the extrema within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.
The given function:
[tex]\rm h(t) = -4t^2+24t[/tex] for the maximum height of the projectile differentiate the given function with respect to 't' and equate it to zero.
[tex]\rm h(t) = -4t^2+24t\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = \frac{\mathrm{d} }{\mathrm{d} x}(-4t^2+24t)\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = \frac{\mathrm{d} }{\mathrm{d} x}(-4t^2)+\frac{\mathrm{d} }{\mathrm{d} x}(24t)\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = -8t+24\\[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x} [h(t)] = 0 \Rightarrow-8t+24=0\\[/tex]
[tex]\rm -8t+24=0\\\rm t= 3 \ sec[/tex]
Here, [tex]\rm \frac{\mathrm{d}^2 }{\mathrm dx^2} \leq 0[/tex]
It means that at t=3, we get the maximum height of the projectile.
[tex]\rm h(3)= -4(3)^2+24(3)\\\rm h(3) = -36+72\\\rm h(3)= 36 \ Feet[/tex]
Thus, the maximum height of the projectile is 36 feet.

solve the equation using the quadratic formula. 3x^2+7x-20=0
Answer:
Step-by-step explanation:
a = co-efficient of x² = 3
b = co-efficient of x = 7
c = constant = -20
Determinant = D = b² -4ac
= 7² - 4*3*(-20)
= 49 + 240
= 289
[tex]x =\dfrac{-b + \sqrt{D}}{2a} ; \ x =\dfrac{-b- \sqrt{D}}{2a}\\\\\\x=\dfrac{-7+\sqrt{289}}{2*3} ; \ x=\dfrac{-3-\sqrt{289}}{2*30}\\\\\\x=\dfrac{-7+17}{6} ; \ x=\dfrac{-7-17}{6}\\\\x=\dfrac{10}{6}; \ x=\dfrac{-24}{6}\\[/tex]

A business has $10,000 in its bank account. In order to build an addition onto its office, it takes out a loan for $30,000 and deposits that money into the bank account. A number line is shown. The number line goes from zero dollars to forty thousand dollars by intervals of five thousand. A point is plotted at ten thousand dollars. What is the new account balance?
Answer:
The new account balance is $40000
Step-by-step explanation:
The number line is not given. However, the question can be solved without it.
Given
[tex]Balance = \$10000[/tex]
[tex]Loan = \$30000[/tex]
Required
Determine the new balance
[tex]New\ Balance = Initial\ Balance + Loan\ Amount[/tex]
[tex]New\ Balance = \$10000 + \$30000[/tex]
[tex]New\ Balance = \$40000[/tex]
Hence:
The new account balance is $40000
