the diameter of a circle is 32 cm. find its area to the nearest whole number.
answer attempt 1 out of 2
a = cm² submit answer

Explanation:

Step1: Calculate the radius

The radius \( r \) of a circle is half of the diameter \( d \). Given \( d = 32\) cm, so \( r=\frac{d}{2}=\frac{32}{2}=16\) cm.

Step2: Use the area formula

The area formula of a circle is \( A=\pi r^{2}\). Substitute \( r = 16\) into the formula: \( A=\pi\times(16)^{2}\).

Step3: Round to the nearest whole number

Rounding \( 804.24704\) to the nearest whole number gives \( 804\).

Answer:

\(804\)
