A circle has a circumference of 907.46 units.

What is the diameter of the circle?

Answer: 289

Step-by-step explanation: The equation for circumference is dπ=C. So divide 907.46 by 3.14 which is 289 units.

C = π d

C = circumference

d = diameter

π = circumference to diameter ratio

C = 907.46 units (given)

π = 22/7 or 3.14 approximate

d = ?

now substitute the given values in the formula, we have

907.46=22/7 x d

907.46 x 7 = 22d

d = 907.46 x 7:22

d = 288.7372 or round about

d = 289
