Question

Please help I suck at this

Answer 1

383 which is 400 m^2 to the nearest hundredth

Explanation:

`\pi {r}^(2)`

use the equation for area of sector and multiply by 3/4

Answer 2

383.03 m²

Explanation:

area of circle = πr²

We use 3.14159 for π (pi).

The radius, r, is 12.75 m.

area = 3.14159 × (12.75 m)²

area = 3.14159 × 162.5625 m²

area = 510.70472 m²

The area of the full circle is 510.70 m²

The shaded area is 3/4 of the circle.

shaded area = 3/4 × 510.70 m²

shaded area = 0.75 × 510.70 m²

shaded area = 383.03 m²
