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
