Question

Please, please HELP!!!

If the diameter of a circle is 12, what is the area and circumference?

Answer 1

Answer:

circumference: 37.7

area: 113.1

Step-by-step explanation:

for the future look up '___ of a circle'

and enter the radius (if u are given the diameter divide it by 2)

Answer 2

Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04
