Write and equation for the area of the circle given the following conditions:

d = 15

A = π (7.5)²

Step-by-step explanation:

A = π r²

A = area

r = radius

radius is half of the diameter, so the radius is half of 15, therefore radius is 7.5. Plug that in, and you get the equation. To solve, just put  π (7.5)² into your calculator to get the area

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
