What is the formula in finding the height of a cylinder?
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
What is the formula in finding the radius of a cylinder?
The answer depends on what information you are given: volume and height, or surface area and height, etc.
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
Formula for finding volume and area of sphere?
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
What is the formula in finding the height of a cylinder?
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
What is the area of a cylinder with a diameter of 4 and radius of 7?
The given dimensions are impossible and so finding its area can't be worked out.
What is the formula in finding the radius of a cylinder?
The answer depends on what information you are given: volume and height, or surface area and height, etc.
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is the formula for finding the radius?
The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
Formula for finding volume and area of sphere?
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
Formula for finding the area if you have radius?
Area of a circle = pi*radius2
What are 5 formulas that use pi in geometry?
Circumference of a circle given radius Area of a circle given radius Volume of a sphere given radius Surface area of a sphere given radius Converting degrees to radians or vice versa
What is the equation for finding area in a circle?
It's radius x radius x pi.
What is theformula for finding the area of circle when you know its radius?
area = (pi)r2
