Question

What is the area of the sector formed by RAP? The radius is 10 inches.

Answer 1

Answer:

≈ 39.3 in²

Step-by-step explanation:

The area of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × $\frac{45}{360}$

  = π × 10² × $\frac{1}{8}$

  = $\frac{100\pi }{8}$ ≈ 39.3 in² ( to 1 dec. place )
