Question

What is the best approximation for the area of a circle with a diameter of 19 meters?

Use 3.14 to approximate pi.

29.8 m²

59.7 m²

283.4 m²

889.9 m²

Answer 1

283.4m2 short answer ;)

Explanation:

Answer 2

`A = \pi r^(2)` is the equation used for determining area from radius. We're given diameter, so to get the radius simply divide by 2. 19/2 = 9.5.


`A = (3.14)(9.5)^(2)`, when solved, equals
`283.385 m^(2)`. After rounding to the nearest tenth, we get
`283.4 m^(2)`
