S = C2/pi
where S is the surface area, C is the circumference.
The approximate surface area of a sphere with circumference 37.68km is 452km
Surface area = 53.794 units2
Circumference of a circle given radius Area of a circle given radius Volume of a sphere given radius Surface area of a sphere given radius Converting degrees to radians or vice versa
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi

circular calculations. circumference, area of circle, vol of sphere, surface area of sphere, etc.
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
4*pi*r2. because surface area is equal to circumference of circle.
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
pie times diameter is the circumference of a circle. a sphere is a 3-dimensional object and you dont take the circumference but rather you take the surface area. the circumference is to measure the total outside distance around the circle. the surface area is the measure the total outside distance around the sphere. remember a sphere is like a ball that is rounded. a circle is just a circle and can only be 2-dimensional.. like on paper
They can be: volume, surface area, radius, diameter, circumference, axis and its hemisphere
Circumference = 27 cm So radius, r = 27/Pi = 4.297183 cm Then surface area = 4*Pi*r2 = 232.05 cm2
Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3
