Find the circumference and area of a circle with a diameter of 22 inches. leave your answers in terms of pi.

a. c = 11π; a = 44π
b. c = 22π; a = 44π
c. c = 11π; a = 121π
d. c = 22π; a = 121π

d. C = 22π   ; A = 121π

Step-by-step explanation:

Circumference of a circle with diameter d is given by :-

Given: Diameter of circle = 22 inches

Therefore, the circumference of circle is given by :-

Area of circle: , where r is radius of circle.

Since diameter = 22 inches, then radius = 11 inches   [Half of diameter]

Now, Area of circle:
