Answer: V=282.74
Step-by-step explanation:
We are given the volume of a cylinder, which is V=πr²h. Luckily, we are given the radius and height, so all we have to do is to plug them into the formula.
V=π(3)²(10) [exponent]
V=π9(10) [multiply]
V=90π
If we plug this into the calculator, we get V=282.74.

A triangle that has sides with lengths of 3cm, 6cm and 9cm is not a right-angled triangle.
What is the Triangle Inequality Theorem?In Mathematics, the Triangle Inequality Theorem is represented by this mathematical expression:
b - c < a < b + c
Where:
a, b, and c represent the side lengths of this triangle.
By applying the Triangle Inequality Theorem to the side lengths of this triangle, the right-angled triangle that can be formed would be determined as follows:
6 + 3 > 9
9 > 9 (False and not a right-angled triangle).
In conclusion, we can logically deduce that the two (2) short side lengths does not exceed the long side lengths and as such it is not a right-angled triangle.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
Two triangles are comparable if they have two pairs of sides that are in the same ratio and if the included angles are likewise equal.
The square of any ratio between any two matching sides of two comparable triangles is equal to the ratio of their areas. As an illustration, Area of ABC/Area of DEF equals (AB)2/(DE)2 = (BC)2/(EF)2 = (AC)2(DF)2 for any two comparable triangles ABC and DEF.

Rachel's personal loan of $4,500 with a 12% annual interest rate for 36 months will have a finance charge of $6,230.16, meaning that she will need to pay a total of $10,730.16 to pay off the loan amount.
The finance charge on Rachel's loan can be calculated by multiplying the loan amount by the interest rate and then multiplying by the loan term (in months).
Finance Charge = (Loan Amount x Interest Rate x Loan Term)
Finance Charge = ($4,500 x 0.12 x 36 months)
Finance Charge = $6,230.16
The finance charge on Rachel's loan can be calculated by multiplying the loan amount by the interest rate and then multiplying by the loan term (in months). In this case, Rachel took out a $4,500 loan with a 12% annual interest rate for 36 months. The total finance charge for this loan can be calculated as follows: Finance Charge = ($4,500 x 0.12 x 36 months) = $6,230.16. This means Rachel will need to pay a total of $10,730.16 to pay off the loan, including the finance charge. This also means that Rachel's monthly payments of $173.06 will go towards the principle balance of the loan and the interest accrued during each month.

What is Commission?A commission is a percentage of total sales as determined by the rate of commission. A commission is a profit paid due to making a sale.
commission=rate of commission⋅total sales.
To find the commission on a sale, multiply the rate of commission by the total sales.
commission = rate of commission⋅total sales.
commission = 7.75% x $4,300
commission = 0.0775 x $4,300
commission = $333.25
Danielle's earnings will be the addition of both her commission and base salary
Total = commission + base salary
Total = $333.25 + $725
Total = $1,058.25

Can you spot any mistakes below?
Q1. Make y the subject of the formula:
k=y(squared)+a
√k =y+a
√k - a=y
y=√k-a
Q2. Express in terms of t
t=v/4+1
t-1+v/4
t-1/4=v
Please help I do not know if there are any mistakes
In Q1, The equation k = y² + a is correct,
To make y the subject of the formula, √k = y + a is incorrect, it should be √k = y + √a
√k - √a = y
In Q2, t = v/4 + 1 is correct
t - 1 + v/4 is incorrect, it should be t - 1 = v/4
t - 1/4 = v
so the correct answer is t-1/4=v
