What is pi r squared times three to the fourth power?
(pi) R2 x 34 = 81 pi R2
How do you find the height of a cylinder?
The formula for the volume of a cylinder, which is h(pi)r2, is the area of the base (pi)r2 multiplied by the height (h). If you are given the diameter instead, remember that the diameter is twice the radius.So if we know that V = h(pi)r2, we can rearrange the formula in order to find the height.Divide the whole equation by (pi)r2. The result is: V ÷ (pi)r2 = h OR h = V ÷ (pi)r2.The formula h = V ÷ (pi)r2 means the height (h) is equal to the volume (V) divided by the area of the base (pi)r2.
What is the total area of a cylinder?
The volume of a cylinder is equal to Pi times the square of the radius times the height of the cylinder. Pi*r2*h. Pi*r2 is the area of the base of a cylinder. The surface area of a cylinder is 2*Pi*r2+Pi*2r*h. 2*Pi*r2 is the area of the base of the cylinder times two to account for both bases. Pi*2r*h is the circumference of the base times the height of the cylinder
What is the diameter of a circle whose area is 16π?
If radius = r, then area = pi*r2 So 16*pi = pi*r2 so that r2 = 16 and so r = 4 Then diameter = 2*radius = 8 units.
How do you find the radius of a cone knowing only the height and volume?
The volume v = (1/3) pi r2 h You just need to rearrange this to get r on its own. Multiply both sides by 3: 3v = pi r2 h Divide both sides by pi: 3v / pi = r2 h Divide both sides by h: 3v / (pi h) = r2 We get an answer for the radius which is the square root of 3v / (pi h)
Express the radius of a circle as a function of its area?
A = (pi)r2 A/pi = r2 √(A/pi) = r
How do you find the radius of a circle if you have area?
The area of a circle is pi * r2 where r is the radius Solving for r, where A is the area: A = pi * r2 A/pi = r2 r = sqrt(A/pi)
What is the circumference of a sphere with a radius of 1.98 km?
The answer is Pi R2 The answer is Pi R2
What is the formula for calculating surface area of a hemisphere?
The surface area of a whole sphere, of radius r, is 4*pi*r2.The area of the curved surface of a hemisphere is, therefore, 2*pi*r2.The area of the flat surface is that of a circle of radius r, that is = pi*r2.So the total surface area of a hemisphere is 2*pi*r2 + pi*r2 = 3*pi*r2.
What is the answer for V equals π r2h for h?
V = (pi) R2 hDivide each side of the equation by (pi)R2 :h = V/(pi)R2
What is the radius of a circle if the area is 324 square inches?
A=Pi*r2 324=Pi*r2 r2=324/Pi r=√(324/Pi) r~=10.155 inches
What are some formulas that include pi?
Area of a circle = pi*r2 Circumference of a circle = 2*pi*r or pi*d Volume of a sphere = 4/3*pi*r3 Surface area of a sphere = 4*pi*r2 Volume of a cone = 1/3*pi*r2*height Volume of a cylinder = pi*r2*height
What is pi r squared times three to the fourth power?

What is the area of a circle with a radius of 5 using 3.14?
Area = pi*r2 = 78.5 square units, approx.Area = pi*r2 = 78.5 square units, approx.Area = pi*r2 = 78.5 square units, approx.Area = pi*r2 = 78.5 square units, approx.
What is pi r2 divided by 2 plus 80 times 50?
(pi*r2)/2 + 4000
13 Find the diameter of a circle if the area is 346.36 square yards?
Area of circle (A) = Pi*r2 346.36 = Pi*r2 r2=346.36/Pi r=√(346.36/Pi) d=2r=2√(346.36/Pi) d ~= 21.000 yards
