Question

The circular opening of a tunnel has a

circumference of 36 meters. Which equation can
be used to find d, the diameter of the tunnel
opening in meters?

A n • 36= d
B 36(over 2pi) = d
C 2• pi • 36=d
J. 36( over pi) = d
​

Answer 1

J

Explanation:

36 = pi × d

d = 36/pi

Answer 2

J. 36(over pi) =d

Explanation:

as we know that ratio of circumference and diameter is π

i.e, c/d =π

i.e, c=dπ

i.e, d= c/π

i.e, d= c(over pi) =36(over pi)
