Question

The point (6, 0) lies on a circle with the center at the origin. What is the area of the circle to the nearest hundredth? Use 3.14 for π.

Answer 1

The area of the circle is about 113.04 square units.

Explanation:

A = πr²

Use the formula.

A = π(6)²

Substitute. Use 6 for r.

A ≈ 3.14 × 6²

Substitute. Use 3.14 for π.

A ≈ 3.14 × 36 Evaluate the power.

A ≈ 113.04 Multiply.

Answer 2

Area of the circle = pi r^2

So 6 to 0 is 6

The radius is 6
pi = 3.14 approximately

So area = 3.14 x 6^2
= 36 x 3.14
=113.04
