The radius of a circle is 5 inches What is the circumference of the circle?
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
What is the radius in inches of the wheel A wheel made 3000 revolutions while traveling 45000 pi inches in a stright line along the ground . give answer and explanation?
If the wheel made 3000 revolutions and covered 45000 pi inches, then one revolution would cover 15 pi inches. That is the circumference. The circumference is equal to 2 times the radius times pi. Then the radius is 7.5 inches.
What is Pi times radius times radius?
The answer is Pi times radius squared. Although you can't know anymore since you don't give what the radius is. Although, Pi can be simply referred to as 3.14

the same as pi squared, which is 9.86960440109
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How find area of a circle if diameter is 15?
pi * 225/4 Radius is 15/2 pi r2 = pi * (15/2)2 = pi * 225/4
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
