Question

1. Find the circumference of a circle, whose diameter is:
(1) 2.5m (THE ANSWER MUST BE 7.85)(PLEASE ANSWER IT FAST)^-^​

Answer 1

diameter = 2.5m

radius = diameter/2 = 2.5/2 = 1.25m

circumference of a circle C=2πr

= 2 × 3.14 × 1.25

= 7.85m

Answer 2

Step-by-step explanation:

d=r/2

2.5/2

1.25m

circumference = 2pier

2×22/7×1.25

7.85 m
