Question

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

Answer 1

Answer:

Step-by-step 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

Answer:

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

Step-by-step 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
