Question

calculate the diameter and radius of a circle, whose circumference is 26.4 m .​

Answer 1

circumference of circle=26.4

we have to find radius&diameter

As we know that

$circumference = 2\pi \: r$

$2\pi \: r = 26.4 \\ 2 \times 3.14 \times r = 26.4 \\ 6.28 \times r = 26.4 \\ r = \frac{26.4}{6.28} \\ r = 4.2 \\ dimeter = 2 \times r \\ = 2 \times 4.2 \\ = 8.4m$
