Answer: 31.4cm
Explanation:
Given : Diameter= 10cm
= 3.14
Solution : Radius= Diameter/2 = 10/2 = 5cm
Circumference = 2r = 2 x 3.14 x 5 = 3.14 x 10 = 31.4cm
Therefore, the circumference of a circle with diameter 10cm is 31.4cm
Answer:
C = 10π cm
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
here the diameter = 10 , then r = 10 ÷ 2 = 5
C = 2π × 5 = 10π cm
