Question

If the circumference is 90cm what is the radius

Answer 1

circumference = 90cm
2pie r=90
pie r=45
r=45*7/22
r=315/22
r=14.32

Answer 2

Hey friend,
Here is the answer:
$circumference \: = 2\pi \: r \\ \\ 90 = 2 \times \frac{22}{7} \times r \\ \\ 90 = \frac{44}{7} \times r \\ \\ r = 90 \times \frac{7}{44} \\ \\ r =45 \times \frac{7}{22} \\ \\ r = \frac{315}{22} \\ \\ in \: decimal = 14.31(approx)$

Hope this helps!!!
