Question

Martina used 3 as the value of pi to estimate the area of a circular patio that had a diameter of 26 ft.

What was Martina's estimate?

Answer 1

507 ft²

Explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

given diameter = 26 then r = 26 ÷ 2 = 13 , so

A = π × 13² ≈ 3 × 169 = 507 ft²
