Question

Calcualte the area area of circle x if the diameter is 13 inches

Answer 1

Explanation:

Area = πr^2

r = diameter/2

r = 13/2

Area= 22/7 × (13/2)^2

= 22/7 × 169/4

Area = 132.79sqaure inch

Answer 2

The area of circle x is 132.79 square feet (132.79 ft^{2} }

Explanation:

Diameter (d) = 13 inches

Radius (r) = d/2 = (13/2) inches

Π = 22/7

Area of circle x = π(r)^2

= 22/7 x (13/2)^2

= 22/7 x 42.25

= 929.5 /7

= 132.79 square inches
