you divide the surface area by the circumference.
S = C2/pi where S is the surface area, C is the circumference.
Surface area = 53.794 units2
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
The approximate surface area of a sphere with circumference 37.68km is 452km
you divide the surface area by the circumference.
First find the radius by dividing 23 by 2*pi which works out as 3.660563691 Surface area of the sphere = 4*pi*3.6605636912 = 168.3859298 or about 168 square mm
S = C2/pi where S is the surface area, C is the circumference.
Surface area = 53.794 units2
First find the radius by dividing 19 by 2*pi which is 3.023943919 cm Surface area of a sphere (the ball) = 4*pi*radius2 Surface area = 4*pi*3.0239439192 => 114.9098689 Surface area of the ball: 115 square centimeters correct to three significant figures.
Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)
2 X Pi X radius X height = area Circumference X height = area (times two if you want inside and outside assuming the walls are of zero thickness)
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
yes heat loss is affected by diameter, circumference and surface area. Heat loss depends on the surface area : volume ratio.......the larger this is the more heat is lost if a cylinder having the same volume but a different surface area...(therefre radius and circumference is different)........the cylinder having the larger surface area will loose heat fastest
The formula for finding the surface area of a hollow cylinder is: 2πrh + 2π(R+r)h, where r is the inner radius, R is the outer radius, and h is the height of the cylinder.
The approximate surface area of a sphere with circumference 37.68km is 452km
Take the circumference and multiply it by it's height to get the lateral surface area.
