Question

Find the daimeter of a circle whose circumferencfe is by 15.70m

Answer 1

circumference = 2pir
15.70 = 2×22/7 ×r
r= 15.70/6.28
r = 2.5
and diameter = 2r = 5m

hope it helps
mark me as brainliest

Answer 2

circumference of a circle=2*3.14*r. ( where r=radius)
15.70=2*3.14*r
15.70upon3.14=2r
2r=5
d=5m(d=2r)
answer is 5m
