Question

Calculate the area and perimeter of the circle.

Answer 1

Explanation:

The area of a circle of radius r is A = (pi)r^2. In this case, r = 2 units, so the area is A = (22/7)(2 units)^2 = 88/7 units^2

The perimeter of a circle of radius r is P = C = circumference = 2(pi)r. In this case, r = 2 units, so the circumference/perimeter is

C = 2(3.14)(2 units) = 2(22/7)(2 units) = (22/7) units

Answer 2

Answer: See below

Radius appears to be 3 in the picture so....
Formula : Area of a circle: A =pi * r^2
A = 3.14*(3)^2 = 28.26

Perimeter of a circle is known as circumference

Formula: Circumference of a circle: C = 2* pi * r
C= 2 *(3.14)*3 = 18.84
