Q. V=31πr2hThe formula gives the volume V of a right circular cone with radius r and height h. What is the volume, in cubic meters, of a right circular cone with a radius of 4 meters and a height of 3 meters?Choose 1 answer:(A) 16π(B) 36π(C) 48π(D) 144π
Formula for volume of cone: The formula for the volume of a right circular cone is given by V=31πr2h, where r is the radius and h is the height of the cone. We need to substitute the given values of r=4 meters and h=3 meters into the formula to find the volume V.
Substitute given values: Substitute the given values into the formula: V=31π(4)2(3).
Calculate radius squared: Calculate the radius squared: (4)2=16.
Multiply radius squared by height: Multiply the radius squared by the height: 16×3=48.
Multiply by pi and divide by 3: Multiply by π and divide by 3 to get the volume: V=31×48×π.
Calculate final volume: Calculate the final volume: V=16π cubic meters.
