28. Area Rug' A circular area rug has a radius of 3 feet. How much area does the rug
cover?
(The area of a circle is A = Trwhere
3.14 and r is the radius.)
3 ft

28.274 sq ft

Step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
