Question

Question 1: Identify the area of sector MOR in terms of π and rounded to the nearest hundredth.

A.) ≈ 49π in2 ≈ 153.94 in2

B.) ≈ 7π in2 ≈ 21.99 in2

C.) ≈ 17.96π in2 ≈ 56.42 in2

D.) ≈ 8.98π in2 ≈ 28.22 in2

Question 2: Identify the measure of arc PR.

A.) 90°

B.) 45°

C.) 128°

D.) 28°

Please give explanation and answer!

Answer 1

Hi,

The first question I figured out the area of the circle given the radius = 7. pi r^2

then the figured out the fraction of the circle intercepted by 66 degrees.

Then I took the fraction and multiplied by the area of the entire circle. answer d.for the area of sector MOR

Can you follow this setup?

For the the second problem. Arc PT is 90 degrees,and arc P Q R and arc PT together form a semicircle containing 180. Arc P Q R is 90 degrees answer A.

Hope this helps
