What is the radius of a sphere if the volume is 523.6cm cubed?
4/3*pi*radius3 = 523.6 Making the radius the subject of the above gives it a value of 5.000003897 or about 5 cm
If a radius of a sphere is doubled what happens to the volume?
The volume is proportiuo9nal to the cube of the radius, so doubling the radiuscauses the volume to increase to (2)3= 8 times its original value.
What is the volume of a sphere with a diameter of 4 meters?
Volume of a sphere equals 4 thirds times pi times the radius cubed. The radius here is 2 meters because the radius is one half the diameter. So plugging in the radius yields an exact result of 32pi ----- cubic meters 3 Or an equally correct but less precise value of 33.5103 cubic meters.
What is the radius of a tennis ball with a surface area of 28 in?
Surface area: 4*pi*radius2 = 28 Making the radius the subject of the above gives it a value of 1.49270533 or about 1.5 inches
What is the volume of a sphere with 16 inche diameter?
To find the volume of a sphere, you can use the formula V = (4/3)πr^3, where r is the radius of the sphere. Since the diameter is 16 inches, the radius would be half of that, which is 8 inches. Plugging this value into the formula, you get V = (4/3)π(8)^3 = (4/3)π(512) = 2144π cubic inches. So, the volume of the sphere is 2144π cubic inches.
What is the value of A(5) the surface area of a sphere with a radius of 5 units?
It is 314.159 or 100*pi square units.
What is the radius of a sphere when the surface area is 803.84?
Surface area: 4*pi*radius2 = 803.84 Making the radius the subject of the above gives it a value of 7.9979719132 or about 8 units in length. Check: 4*pi*7.99797191322 = 803.84 square units
What is the value of V(4) the volume of a sphere with a radius of 4 units?
Volume of the sphere: 4/3*pi*4 cubed = 268.083 cubic units rounded to 3 decimal place
What is the value of V(3) the volume of a sphere with a radius of 3 units?
It is: 4/3*pi*3 cubed = 36*pi cubic units
Surface area equals 4ar2 where are is the radius of the sphere a is a constant that is roughly equal to 3 what is the surface area of a sphere with a radius of 7 meters?
Using your value of a, the answer is 4x3x7x7 square metres. More accurate to use the correct value of a, which is pi (ie nearer to 3.142) 588.2 m2
What is the volume of a sphere with a radius of 3.1?
The formula to calculate the volume of a sphere is V = (4/3)πr^3, where r is the radius of the sphere. Given a radius of 3.1, we substitute this value into the formula: V = (4/3)π(3.1)^3. Calculating this gives us V ≈ 127.6 cubic units.
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.
How do you find the volume of a sphere if the radius is a negative number?
radius is a scalar quantity, it can not have a negative value.
What Pi used for?
Pi has many usages in mathematics some of which are:- Area of a circle = pi*radius squared Circumference of a circle = diameter*pi or 2*pi*radius Surface area of a sphere = 4*pi*radius squared Volume of a sphere = 4/3*pi*radius cubed Volume of a cone = 1/3*pi*radius squared*height The value of pi is found by dividing the circumference of a circle by its diameter
What is the approximate volume of the sphere if the surface area is 482.8mm squared?
Volume of a sphere is given by V = 4/3 x π x r3. So for the calculation of volume we should have the value of radius. The value of radius can be known from the given surface area. Surface of a sphere = 4 x π x r2 482.8 mm2 = 4 x π x r2 r2 = 482.8/(4 x π) mm2 r2 = 38.42 mm2 r = 38.421/2 mm = 6.19 mm So Volume of Sphere can, now, be calculated: V = 4/3 x π x 6.193 mm3 = 993.48 mm3.
What is the surface area of a sphere with volume of 140cm?
Volume: 4/3*pi*radius3 = 140 By making the radius the subject of the above gives it a value of 3.221166265 cm Surface area: 4*pi*3.2211662652 = 130.387557 square cm
What is the surface area of a sphere when its volume is 288pi cubic cm showing work?
To find the surface area of a sphere when its volume is 288π cubic cm, we first need to find the radius of the sphere. The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius. Given that the volume is 288π, we can solve for r: 288π = (4/3)πr^3. Solving for r, we get r = 6 cm. Next, we can find the surface area of the sphere using the formula A = 4πr^2, where r is the radius. Plugging in the radius of 6 cm, we get A = 4π(6)^2 = 144π square cm. Therefore, the surface area of the sphere is 144π square cm.
