Question

Find the area of a circle with a radius of 6.7 m to the nearest square unit

Answer 1

Answer:

141 Square units.

Step-by-step explanation:

Area of a circle is equal to pi*radius squared.

$A = \pi \times 6.7^{2} \\A = 141.026....\\A \approx 141 u^2$

Answer 2

Answer:

A = 141 m²

Step-by-step explanation:

The formula of an area of a circle with radius r:

$A_O=\pi r^2$

We have r = 6.7m. Substitute:

$A_O=\pi\cdot6.7^2=\pi\cdot44.89\approx3.14\cdot44.89=140.9546\approx141\ m^2$
