Question

What is the exact area of a circle with a diameter of 50 centimeters?

A.87.9 square centimeters
B.379.9 square centimeters
C.1962.5 square centimeters
D.4923.5 square centimeters

Answer 1

Answer: C) 1963.5

Solve for area. Pi (π) is a non-algebraic number that represents the ratio of the distance around the circle (circumference) to its diameter, usually estimated as 3.14. To solve for area, square the radius (radius times radius) then multiply by 3.14.
