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 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 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 the volume of this cylinder with a 3in side length and a 5cm radius?
Volume = pi*r2*h = 92.76 cm3 Volume = pi*r2*h = 92.76 cm3 Volume = pi*r2*h = 92.76 cm3 Volume = pi*r2*h = 92.76 cm3
What is pi r squared times three to the fourth power?
(pi) R2 x 34 = 81 pi R2
What is pi r2 divided by 2 plus 80 times 50?
(pi*r2)/2 + 4000
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
How do you calculate the area of a cylinder?
Pi times Radius times Radius times Height.Area of cylinder depends on which side you want.The top and bottom parts = Pi times Radius times Radius. (∩r2)The round part = Pi times Diameter (or 2 * Radius) times Height (∩Dh)Volume = Pi times Radius times Radius times Height (∩r2h)Note: ∩=PiThe area is the outer surface.The surface of a right truncated circular cylinder is calculated as follows:PI * r2 * hwhere PI is the irrational: 3.15158...r is the radiush is the heightIf it is a solid (or a closed shell) then you have to add the ends:twice the area of the circular cross section: PI * r2The 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 does pi radius 2 mean?
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
What is the diameter of a circle with 64 as a diametr?
The answer is 3215.36. The formula for pi is A= pi times radius squared or A=pi r2
What is the formula for finding the area of a cirlce?
pi times radius squared: a=pi x r2
What will be the volume of a cylinder that's dimensions are doubled?
The volume of a cylinder is:V1 = pi r2 hV2 = pi (2r)2 2h = pi 4r2 2h = 8pi r2 hV1/V2 = (pi r2 h)/(8 pi r2 h)V1/V2 = 1/8Thus, V2 is 8 times bigger than V1.
Formula of area of circle?
Area= pi times the radius squared or A=Pi(R)^2
Express the radius of a circle as a function of its area?
A = (pi)r2 A/pi = r2 √(A/pi) = r
What is the Radius of a circle with an area of 125 inches?
The formula for area of a circle is: A = pi * r2 (area equals pi times radius squared) There fore if you plug in the numbers you know (pi = 3.14) you get 125 = 3.14 * r2 39.8 = r2 r = 6.31 inches
How do you find the value of h when pi times r to the second power times h divided by 3?
There is not enough information to answer the question as it is stated. If the value of pi*r2*h/3 is known (to be k, say) then h = 3*k/(pi*r2)
