Weegy: Formula:
Circumference = 2*pi*radius;
= 3.14*diameter;
= 3.14*8;
= 25.12 ft.
For diameter = 16 ft., Circumference = 50.24 ft.
For diameter = 64ft., Circumference = 200.96 ft.
User: Find the radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. (Use = 22/7)
Weegy: Pi*r^2 = 2 x 11 (22/7)r^2 = 22 r^2 = 7 r = sqrt 7 ft. The radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. is sqrt 7 ft.
User: Find the radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. (Use = 22/7)
Weegy: Pi*r^2 = 2 x 11 (22/7)r^2 = 22 r^2 = 7 r = sqrt 7 ft. The radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. is sqrt 7 ft.
User: A circle has a radius of 8 inches. Find the area of a sector of the circle if the sector has an arc that measures 45°.
Weegy: A circle has a radius of 8 inches. The area of a sector of the circle if the sector has an arc that measures 45? is (45/360)*3.14*8^2 = 25.12 square inches.
User: Find the approximate area of a circle with radius equal to 8 ft. (Use = 3.14.)
User: Find the length of an arc of an 8" radius circle if the arc measures 45°
Weegy: The length of an arc of an 8" radius circle if the arc measures 45? is S = r = 8*45 = 360 inches.
