Question

The area, A, of a circle is given by A = π r2, where r is the radius of the circle. Round all values to the nearest whole number before substituting into the formula in order to estimate the area of a circle with radius 11.3 centimeter

Answer 1

363

Explanation:

i just did the quiz

Answer 2

A =363 cm^2

Explanation:

A = π r^2

r = 11.3

Rounding to the nearest whole number

r =11

pi = 3.14

Rounding to the nearest whole number

pi = 3

A = 3 * 11^2

A = 3 *121

A =363 cm^2
