Question

What is the best approximation for the area of this circle?

Use 3.14 to approximate pi.
The radius is labled 4.
PLEASE HELP!

12.6 m²

25.1 m²

50.2 m²

158.0 m²

Answer 1

Answer: [C]: 50.2 m²
__________________________

Since: Area of a circle: A =
`\pi` * r² ';

And: A =
`\pi` = 3.14 * 4² = 3.14 * 16 ;

We know that the area will be a bit more that ( 3 m * 16 m = 48 m²) ;

And, Answer choice: [C]: 50.2 m² ; is the closest value.

Answer 2

Area of circle = πr² = 3.14×4² = 50.24m²

The best approximation is C.
