Question

Suppose that circles R and S have a central angle measuring 80°. Additionally, circle R has a radius of 3 ft and the radius of circle S is 6 ft. If the measure of the sector for circle R is 2π ft2, what is the measure of the sector for circle S? A) 8π ft2 B) 9π ft2 C) 10π ft2 D) 12π ft2

Answer 1

8π ft2

3262 = 2πx
x = 8π

When circles have the same central angle measure, the ratio of measure of the sectors is the same as the ratio of the radii squared.

Answer 2

A) is the correct answerrrrr
