Q. A sumo wrestling ring is circular and has a circumference of 4.6π meters.What is the area A of the sumo wrestling ring in square meters? Give your answer in terms of π.A=□m2
Circle Circumference Formula: The circumference C of a circle is given by the formula C=2×π×r, where r is the radius.
Calculate Radius: Given the circumference is 4.6π meters, we can set up the equation 4.6π=2×π×r to find the radius.
Circle Area Formula: Divide both sides by 2π to solve for r: r=2π4.6π=2.3 meters.
Substitute Radius: The area A of a circle is given by the formula A=π⋅r2.
Calculate Area: Substitute r=2.3 meters into the area formula: A=π×(2.3)2.
Calculate Area: Substitute r=2.3 meters into the area formula: A=π×(2.3)2.Calculate the area: A=π×5.29 square meters.
