How do you find the surface area of a sphere with the diameter?
Surface area of a sphere: A = 4πr.
How do you find area with diameter and circumference?
If you want to find the area of a circle with a circumference of 1 meter, do the following: Divide the circumference by π. This is the circle’s diameter, in this case, 31.8 centimeters. Divide by 2.
How do you find surface area using circumference?
The area of a circle is given by the formula A = π r2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r. If we “solve for r” in the second equation, we have r = C / (2 π ). Now we use this to replace r in the first equation: A = π [ C / (2 π ) ]2.
What is the circumference of a sphere?
The Circumference of a circle or a sphere is equal to 3.1416 times the Diameter.
What is the surface area of diameter?
The formula of the surface area of a sphere in terms of diameter is given as, πD2 where “D” is the diameter of the sphere. This formula shows the dependence of the surface area of a sphere on the diameter of the sphere.
What is circumference of a sphere?
The Circumference of a circle or a sphere is equal to 6.2832 times the Radius. Circumference = 6.2832 ⋅ R. C = 2 ⋅ π ⋅ R. Figure 3., Circumference is 2 × π × Radius. The Circumference of a circle or a sphere is equal to 3.1416 times the Diameter.
How do you find the surface area?
The total surface area is calculated by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object. This is done using different area formulas and measured in square units.
How do you find the circumference of a sphere?
The Circumference of a circle or a sphere is equal to 6.2832 times the Radius. The Circumference of a circle or a sphere is equal to 3.1416 times the Diameter.
What is the surface area of the sphere?
4πr2
When we write the formula for the surface area of a sphere, we write the surface area of a sphere = 4πr2 = 4(πr2) = 4 × area of a circle.
What is the circumference and diameter of a ball?
What is the formula for finding the circumference of a sphere?
The formula for calculating the circumference of a sphere is 2 x pi x radius. So, the radius of the Earth is 6371 km. Plug that into the formula, and you get 2 x 3.1415 x 6378.1 = 40,074.
What is the formula for sphere area?
Surface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.
What is the volume of a sphere with the surface area?
The surface area and volume of a sphere can be calculated using the formulas: Surface Area = 4 * PI * (radius3) /3. Volume = 4 * PI * (radius2).
What is the lateral surface area of a sphere?
The lateral surface area of a sphere is 4(pi)r^2. The lateral surface area of a cone is (pi)rs. And the lateral surface area of a rectangular box is 2h(l+w).
