Question

What is the area of a circle with a diameter of 16? 8 16 64 128 256

Answer 1

Area is 200.96 square units

Explanation:

Formula for area of a circle:

`area = \pi {r}^(2)`

but radius, r = diameter, d÷2

• r = d/2

`area = \pi {( (d)/(2)) }^(2) \\ \\ area = \pi( (16)/(2) ) {}^(2) \\ \\ area = 3.14 * 64 \\ \\ area = 200.96`
