V=πr2hThe formula gives the volume V of a right circular cylinder with radius r and height h. If the volume of a right circular cylinder with a radius of 4 feet and a height of 30 feet is aπ cubic feet, what is the value of a ?
Q. V=πr2hThe formula gives the volume V of a right circular cylinder with radius r and height h. If the volume of a right circular cylinder with a radius of 4 feet and a height of 30 feet is aπ cubic feet, what is the value of a ?
Identify given values and formula: Identify the given values and the formula to use.We are given the radius r=4 feet and the height h=30 feet. The volume V of a right circular cylinder is given by the formula V=πr2h.
Substitute given values into formula: Substitute the given values into the formula.Using the given radius and height, we substitute into the formula:V=π×(4 feet)2×(30 feet)
Calculate the volume: Calculate the volume V.First, square the radius:(4 feet)2=16 feet2Then, multiply by the height and π:V=π×16 feet2×30 feetV=π×480 feet3
Identify value of 'a' in expression: Identify the value of in the expression .From the previous step, we have . This means that a is the coefficient of ext{π} in the volume expression, which is 480480480.
