The surface area of a sphere with radius R m is 4*pi*R^2 so, in this case, the exact value would be 196*pi. Use the given estimate for pi - which is not visible to us since there is no "above" that is visible.
find the surface area of the cone and add it to the surface area of the base so the formula would be pi radius s plus pi radius squared
The surface area of a sphere is 4 pi R2A = 4 pi (5)2 = 100 pi = 314.16 square meters (rounded)
For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.
The radius is five meters if the circumference is 31.4 meters.
The radius of a circle with a circumference of 41 meters is about 6.525 meters.
The surface area is approximately 300m²- APEX
The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.
The formula to calculate the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7.5 meters into the formula, we get 4π(7.5)^2 = 4π(56.25) = 225π square meters. Therefore, the surface area of a sphere with a radius of 7.5 meters is 225π square meters, or approximately 706.86 square meters.
A cylinder with a radius of 6 meters and a height of 10.5 meters has a surface area of 622.04m2
The radius is 3.45
24
Surface area = 201.06 meters2
A cylinder with a radius of 1 meter and a height of 10 meters has a surface area equal to 69.12m2
995.3 meters2
Surface area = 4*pi*22 = 50.26548246 or about 50 square meters
Based on what? If you know the radius, you can use the formula for a sphere - which is a good approximation in the case of Earth and Moon.
Double the radius to 4.5 meters, which is the diameter. From there, multiply the diameter by Pi to get the circumference:4.5m x Pi = circumference of about 28.27 meters
