b. 716.526 in³
c. 156.52 in³
d. 717.526 in³​


Sagot :

Note: Circle Area Formula: π × radius²

To find the radius use this formula: Diameter ÷ 2

We divide the diameter because the diameter is two times the length of radius.

Radius: 15 ÷ 2 = 7.5

Area: π x 7.5² = 3.14 x 56.25

: 3.14 x 56.25 = 176.625

Then Add the measurement symbol and area symbol

The area symbol: N in²

I think the choices area symbol is 176.625in² not 176.625 in ³.

Answer: B. 176.625 in²
