How long in inches is 15 degrees of circumference on 12 feet outside diameter tank?
Convert the degrees to radians. Also, you need the radius, not the diameter. In that case, the distance along the circle is simply the product of the angle, and the radius.
What is the radius of a circle whose diameter is 15 meters?
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
What is the length of the diameter if its radius is 15 cm?
The length of the diameter will be 30 cm if the radius is 15 cm.
How many inches do you need to cover a 30 inches diameter circle?
What you need is the area of the circle. Area = Pi x r squared where r is the radius. The radius is one-half the diameter so in this case r=15 to square it, multiply it by itself ( 15 x 15 ) so r squared =225 now multiply that by 3.14 . Ans: 706.5 square inches.
What is the radius of the circle that has diameter of 30 feet?
The radius is 15 feet 2r=30 30/2=15 15 is the radius
