What is the surface area of a sphere with the radius 9?
You can find the surface area of a sphere by solving this equation: SA=4(pi)(r)(r) where SA is your surface area, and r is the radius. Your answer comes out to be about 1017.4 square units.
How do you do formula for surface area using sphere?
Surface area of a sphere = 4*pi*radius2
What is the surface area of a 14 inch sphere?
The surface area of a 14-inch sphere is 615.75 square inches.The formula for the surface area of a sphere is 4*pi*r2 where r=radius
Does a sphere have lateral area?
It is incorrect to say that sphere has lateral area. First sphere do not have sides like other geometric figure. In fact a line or plane can intersect the surface of a sphere in just one point. Sphere has no lateral side. It is enough to say surface area of sphere than lateral surface area of the sphere.
Surface area of sphere with volume 0.2 meters?
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.
What is the equation for the surface area of a sphere?
Surface area of a sphere with radius r = 4(pi)r2
Formula for area of a sphere?
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
What is the radius of a sphere that has a surface area of 1742400 squre ft?
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
How do you find the surface area of a hemisphere?
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π r2.
Where might one find the mathematical equation for the surface area of a sphere?
One might find the mathematical equation for the surface area of a sphere in a mathematics textbook. One might also find the equation at online math study groups.
What is the surface area of the earth and how do you come up with the surface area?
Lets pretend that the Earth is a perfect sphere. Surface area of a sphere = 4(pi)(radius)^2. The radius of earth is 6378.1 km. Plug that into your equation and you'll get your answer.
An architect determined the relationship between V the volume of a sphere and S the surface area of the sphere. Write a equation that represents this relationship?
Volume of a sphere = 4/3*pi*radius3 measured in cubic units Surface area of a sphere = 4*pi*radius2 measured in square units
What is the surface area of a sphere?
The formula for the surface area of a sphere is 4*pi*r2
Surface area of sphere?
Surface area of sphere is : A= 4*pie*r^2
What is the surface area of a sphere with radius 6?
The surface area of a sphere with radius 6 is: 452 square units.
What is the formula for the surface area of a sphere with radius r equals 5?
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
What is the surface area of a sphere with the radius 9?
You can find the surface area of a sphere by solving this equation: SA=4(pi)(r)(r) where SA is your surface area, and r is the radius. Your answer comes out to be about 1017.4 square units.
