47.14285714285714
radius = 1/2 of diameter
radius=7.5 which is half of 15
using circumference of circle formula (2 * by pi * by radius)
pi=22/7
2*22/7*7.5=47.14285714285714
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
About 4.712 inches.
It is very easy math!
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter of the pool is 15 feet, so the circumference would be C = π(15) = 47.12385 feet. Therefore, the length around the 15-foot diameter pool would be approximately 47.12 feet.
The formula for area of a circle is Pi x r (squared), A = Pi(rxr). So since the diameter is 30 you divide it by two and get 15 and then square it and multiply it by pi and get 706.86 meters.
15 pi feet
If the diameter of a circle is 15 feet, the circumference will be: 47.12 feet. (C = d x Pi)
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
Assuming the 15 feet is the diameter of the circle. Formula to find the circumference of the circle is pi x diameter. 15 × 3.14 = 47.1 feet So the rope will be 47.1 feet long.
A circumference of 47.1'
Well, isn't that a happy little question! To find the diameter of a circle with a 15-foot circumference, we can use the formula Circumference = π x Diameter. So, we can rearrange the formula to find the diameter, which would be 15 feet divided by π, giving us a diameter of about 4.77 feet. Just remember, there are no mistakes, just happy little accidents in math!
47.1 feet Circumference = 2 x pi x r OR pi x d 3.14 x 15 feet = 47.1 feet
Circumference of the circle: 15 times pi = 47.1238898 meters
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
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.
