Area of a circle: pi*radius squared
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.
C=14pi A= 98pi
Area of any circle = pi*radius squared
Area = pi*r^2 = 153.9 square inches.
Area = 3.14*72 = 153.86 square inches
The radius is 7 inches.
The area of a circle with a radius of 7 cm is: 153.9 cm2
AnswerYou do the radius x radius then multipy it by pi.Say my radius is 7 . 7 x 7 = 4949 x 3.14 (3.14 is pi.)
Radius of the circle will be 7 inches and its area is pi*7^2 = 154 square inches rounded to a whole number
I assume that a 14 inch circle is a circle 14 ionches in diameter. Use the formula Area = Pi x radius of the circle X radius of the circle The radius is half the diameter. Pi is 3.14159 (appx) So the area = 3.14159 X 7 X 7 = 153.937 square inches. Or approximately 154 square inches
Diameter = 14 inches Radius = 14/2 = 7 inches Area of circle = pi x r x r = 3.1415 x 7 x 7 = 153.9335 square inches
