The surface area of a sphere with a diameter of 14 inches is about 615.8 square inches.
153.94 square inches
Area = 153.9 inches2
diameter = 13.99645085 or about 14 inches
153.94 square inches.
If its diameter is 14 then its area is: pi*72 = 153.938 square inches to three decimal places
153.9384 sq inches
154 square inches.
Area of circle =(11/14) * d *d d denotes diameter. For your case answer is 7.1365 inches
A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.
Surface area = pi*72 = 153.93804 square inches
