In order to find the value of the circumference and area of the given circle, use the following formulas:

C = 2πr circumference

A = πr² area

where

r: radius = diameter/2 = 8 cm/2 = 4 cm

π = 3.14

replace the value of r and π into the formulas for C and A:

C = 2(3.14)(4 cm) = 25.12 cm

A = (3.14)(4 cm)² = 50.24 cm²

Hence, the cirumference of the circle is 25.12 cm and its area is 50.24 cm²
