Question

A circular plate has a radius of 22 centimeters. What is the area of the plate? OA) 11 cm² B) 22 cm² OC) 44 cm² OD) 484 cm²​

Answer 1

○ 448π cm²

Explanation:

To find the area of a circle, we use the following formula:

`\boxed{\mathrm{Area = \pi r^2}}`,

where r = radius of circle.

Substituting the value of r = 22 cm into the formula, we get:

`\mathrm{Area = \pi * (22 \space\ cm)^2}`

=
`\mathrm{\pi * 484 \space\ cm^2}`

=
`\mathrm{ \bf484 \pi \space\ cm^2}`

Therefore the area of the circular plate is 448π cm².
