Answer: Perimeter is 22 cm and the area is 38.5 cm^2
Step-by-step explanation:
Given the radius of the circle is r = 3.5 cm
Perimeter of a circle = 2πr
Area of a circle = πr^2
So perimeter of the circle = 2* 22/7 * 3.5
= 2* 22 * 0.5
= 22 cm
Area of the circle = 22/7*3.5*3.5
= 22*0.5*3.5
= 38.5 cm^2
