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.
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
The length of the diameter will be 30 cm if the radius is 15 cm.
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.
The radius is 15 feet 2r=30 30/2=15 15 is the radius
30 inches. The diameter is twice the length of the radius.
The radius of a circle is half the diameter, thus your measurement is 30 inches
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.
30 inches
15 inches.
No ! the radius of the tire has to be 7.5 inches not 15 inches. The diameter has to be 15 inches, and the width has to be compatible with the tire width.
If the diameter is 15 then the radius is 7.5.
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.
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
