Question

What is the area of circle with a radius of 13 milimeters? use 3.14 for pi

Answer 1

530.66mm²

Explanation:

Area of a circle =
`\pi r^(2)`

r(radius) = 13mm

Area = (3.14 × 13²)mm²

= (3.14 × 13 × 13)mm²

= (3.14 × 169)mm²

= 530.66mm²

Hope this helps :))

Answer 2

530.66 mm²

5.3066 cm²

Explanation:

A = π·r²

= 3.14×(13mm)²

= 3.14×169mm²

= 530.66 mm²

= 5.3066 cm²
