Find the diameter of a circle that has a circumference of 74 cm
1 answer:
The diameter is just twice the radius so once we find that we will just multiply it by 2.
Circumference = 2 x
x radius
We just plug in from here.
74 = 2r
Divide by 2 to isolate the r
74 / 2 = r
Leave it as is, because we are not done, we want an exact answer.
As said, we must now multiply by 2 because the diameter is TWICE the radius.
Diameter =
The 2 on the outside and the 2 in the denominator cancel out giving you diameter =
or diameter ≈ 23.5549 cm
Circumference = 2 x
We just plug in from here.
74 = 2
Divide by 2
74 / 2
Leave it as is, because we are not done, we want an exact answer.
