A room is shaped like a square joined by a semicircle. The perimeter around the entire room is about 91 feet, and about 31 feet of the total perimeter comes from the semicircle. B. What is the radius of the semicircle?
C. The room is covered in carpeting. How many square feet of carpeting covers the floor? Round the answer to the nearest whole number.

the answer is 16ft

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
