Question

An architect is planning to put a circular mosaic in the entry of a new building. The mosaic will be in the shape of a circle with radius of 6 feet. How many square feet of tile will be needed for the mosaic? (Round your answer up to the next whole number.)

Answer 1

113 square feet

Explanation:

Since the shape of the mosaic that the architect would be using is circular is shape, the formula to apply to solve this question is area of a circle.

The formula for the area of a circle = πr²

In the above question,Area if a circle = πr²

radius of the circle = r = 6 feet

πr² = π × 6²

113.09733553 square feet

Approximately to the next whole number ≈ 113 square feet.

Therefore, the number in square feet of tiles needed for the mosaic is 113 square feet
