Answer: 131.88 m

Step-by-step explanation: Formula for circumference of a circle: 2 * pi * r

(Using 3.14 as pi)

The first thing you should do is find the radius. The radius is half of the diameter, which is the line through the middle of the circle. Diameter, 42, divided by 2, equals 21. Next you plug the radius, 21, and pi, 3.14, into the 2*pi*r formula:

2 * 3.14 * 21 = 131.88

That's the circumference, hope this helped.

A triangle has three angles that measure 15 degrees, 85 degrees and (4x - 20). What is the value of x?

Lostsunrise [7]

180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25
