diameter of circle 8' 11"

Question

diameter of a circle 8 feet 11 inches

Answer 1

We know that 1 feet = 12 inches

8 feet = 12*8 = 96 inches

Circumference of circle 8feet 11 inches = 96inches.

2*pi*r = 96

r = 96/2*3.14

r = 48/3.14

r = 15.28

d = 2r

d = 2*15.28

d = 30.57

Diameter of circle  = 30.57inches

Comments

Diameter of the circle = 34.07 inches.

Answer 2

Circumference of circle = 8' 11"

1 feet = 12 inches

8 feet = 12 * 8 = 96 inches

Total circumference in inches is  96 + 11 = 107 inches.

Formula for circumference of circle C = pi * d

107 = 3.14d

d = 107/3.14

d = 34.07 inches.

Diameter of circle = 34.07 inches.
