Find the surface area of the sphere in terms of pi

A = 225π in²

Step-by-step explanation:

The equation for the surface area of a sphere is:

A = 4πr²

Plug 7.5 in for r (since r = d/2):

A = 4π(7.5²) = 4π(56.25) = 225π

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
