What is the volume of a sphere with a surface area of 25π yd2?
25 yards2 ????If so....,Area sphere = 4*pi*r2You have area, so....,25 yrd2 = 4*pi*r2r = sqrt(25/4*pi)= 1.41 yards in radius-----------------------------Volume sphere = 4/3*pi*r3Volume = 4/3*pi(1.41 yrd)3= 12 cubic yards===============
If cube has volume 125 cu cm what is area of each face?
A cube with this volume has a total surface area of 150 cm2. Each of its six sides comprises an area of 25 cm2
If the surface area of a cube is 150 what is the volume of the cube?
Well, darling, to find the volume of a cube, you simply cube the length of one side. Since the surface area of a cube is 6 times the side length squared, you can solve for the side length by taking the square root of 150/6. Once you have the side length, just cube it to find the volume. Easy peasy lemon squeezy!
If the volume of a cube is 25 what is its surface area?
Your problem is quite easy...Since getting the volume of a cube is s3 we will do the opposite of it will get its cube root* First get the cube root of 25 = 2.9 (I just round it off but the exact measure is 2.924017738) * Then use the formula 6s2 for solving the surface area SA = (6)(2.9)2= (6)(8.41)SA = 50.46
What is the surface area of a 25 centimeters cube?
A 25 cm cube has all edges with a length of 25 cm. Therefore each face has an area of 25*25 = 625 sq cm. As a cube has 6 faces, the total surface area of the cube is 625*6 = 3750 square centimeters.
What is the surface area of a sphere with a radius of 5 cm?
The surface area is about 314.16 cm2The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 cm, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 cm2*Do not confuse the sphere's surface area formula SA = 4 (pi) r2 withthe formula for the volume of the sphere, which is V = 4/3 (pi) r3
What is the volume of a sphere with a surface area of 25π yd2?
25 yards2 ????If so....,Area sphere = 4*pi*r2You have area, so....,25 yrd2 = 4*pi*r2r = sqrt(25/4*pi)= 1.41 yards in radius-----------------------------Volume sphere = 4/3*pi*r3Volume = 4/3*pi(1.41 yrd)3= 12 cubic yards===============
What is the surface area that has a diameter of 25 in?
The surface area of a sphere with a diameter of 25 inches is about 1,963.5 square inches.
What is the surface area of a sphere when given the volume?
The volume of a sphere is given by the formula 4/3 *pi*r^3 and the surface area is given by the formula 4*pi*r^2. If you know the volume of the sphere you can solve for the radius, then you can plug the resulting value into the surface area formula. For example, suppose I knew that the volume of a sphere was 25 cubic meters: Set 25 equal to the voume formula: 4/3*pi*r^3 = 25 multiply both sides by 3/4 and divide both sides by pi: r^3=pi*75/4 take the cube root of both sides: r=(pi*75/4)^(1/3) Now plug r into my formula for surface area: 4*pi*r^2 = 4*pi*((pi*75/4)^(1/3))^2 And I probably want a decimal approximation for the surface area, that is, I probably want to get rid of the pis and the fractional exponent, so I can plug 4*pi*((pi*75/4)^(1/3))^2 into a calculator to get 190.24385. Then a sphere with a volume of 25 cubic meters has a surface area of 190.24385 square meters.
When the diameter of a sphere is decreased by 25 percent then what per cent does its curved surface area decrease?
The surface area decreases by 43.75%.
How do you find the surface area of a sphere with a radius of 5 inches?
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 in, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 square inches
What is the volume of a sphere with the diameter of 25 cm?
The volume of a sphere with a diameter of 25cm is about 8181.2cm3
When the diameter of a sphere is decreased by 25 percent the what percent does its curved area decreases?
When the diameter of a sphere is decreased by 25%, its curved surface area decreases by approximately 43.75%. This is because surface area is proportional to the square of the radius, so a 25% decrease in diameter leads to a 43.75% decrease in surface area.
The surface area of a sphere depends on its radius so the area is a function of the radius If this function is called Ar use the formula below to compute A5 the area of a sphere with a radius?
A(5) = 4 25
When the diameter of a sphere is decreased by 25 percent by what per cent does its curved surface area decrease?
Surface area, S.A., of a sphere with radius r equals to 4pir2.Since the diameter is decreased by 25%, the radius is also decreased by 25%.That is r - 0.25r = 0.75r.So that S.A. = 4pi(0.75r)2 = 2.25pir2
If a cube has a volume of 125 cubic inches what is the surface area of one face?
25 cubic inches
If cube has volume 125 cu cm what is area of each face?
A cube with this volume has a total surface area of 150 cm2. Each of its six sides comprises an area of 25 cm2
