The area of the circle is the region occupied by it in the two dimensional plane.

Area of a circle is given by ;

The diameter of the circle is 36inches

‎ㅤ‎ㅤ‎ㅤ➙ Radius = D / 2

‎ㅤ‎ㅤ‎ㅤ➙ Radius = 36 / 2

‎ㅤ‎ㅤ‎ㅤ➙ Radius = 18 inches

Therefore, area :

➝ A = πr²

➝ A = 3.14 × ( 18 )²

➝ A = 3.14 × 324

➝ A = 1017.36

Solution:

We know that:

Finding the area of the circle:

Answer:

3. diameter and 4. 14.10cm

Step-by-step explanation:

The distance from point R to point M is the diameter of the circle, it basically cuts the circle is half.

The diameter of a circle is double the radius, 7.5 cm is shown as the radius, so the diameter is 14.10 cm.

Answer:

Answer:

a)

Step-by-step explanation:

Cost function = revenue function - profit function

   = -0.3x² + 150x - [-0.5x² + 250x - 300]

   = -0.3x² + 150x + 0.5x² - 250x +300

  = -0.3x² + 0.5x² + 150x - 250x + 300   {Combine like terms}

  = 0.2x² - 100x + 300

Answer:

25.74 ?

Step-by-step explanation:

It can be deduced that the triangles are similar because the three internal angles are equal for both triangles.

It should be noted that the triangles are similar because the three internal angles are equal.

In this case, the ratio of the corresponding sides are equal and the corresponding angles are congruent.

The width of the river will be:

300/80 = AB/50

AB = (300 × 50)/80

Answer:

A) 30°

Step-by-step explanation:

All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°

Answer:

m Is 30

Step-by-step explanation:

m is 30

because....the sum of angles in a triangle is 180

75+75+m =180

150+m=180

make m the subject of the formula

m=180-150

m=30

Answer:

The total number of nachos sold:49

The total number of pretzels sold:13

Step-by-step explanation:

The numbers of nachos is 49. Each nacho costs 2 dollars.

2 x 49 = 98

Then you subtract that amount to get the amount of money left for pretzels.

137 - 98 = 39

Then you divide 39 by 3 since that's the cost of each pretzel.

39 ÷ 3 = 13

13 is the amount of pretzels you can buy after you buy 49 nachos.

Answer:

y = -4/5x + 3

Step-by-step explanation:

Chose any two points on the line:

(5, -2)

(-5, 6)

Slope = (y2 - y1) / (x2 - x1)

6 -(-2) / -5 - 5

8 / -10

-4/5

Equation:

y = mx + b

Plug in x and y using any coords and then plug in m (the slope):

-2 = -4/5 * 5 + b

-2 = -20/4 + b

-2 = -5 + b

Add 5 on both sides:

3 = b

Now our equation is:

y = -4/5x + 3

Answer:

$0.45

Step-by-step explanation:

To answer this question, we first have to subtract the delivery fee from the total cost:

1430 - 35 = 1395

Now, we divide this number by the total amount of candy bars:

1395 / 3100 = 0.45

So, each candy bar costs $0.45
