Question

A semi-circle shaped rug has a diameter of 4 feet. What is the area of the rug?

Answer 1

Answer:

$6.29$

Step-by-step explanation:

Let;

area =

$0.5 \times \pi {r}^{2}$

which is for the semi circle

BUT;

diameter is 4 so finding radius = 4 ÷ 2 = 2

So the r as radius is 2

CALCULATION

$0.5 \times 22 \div 7 \times 2 {}^{2}$

=

$6.29$

Answer 2

Answer:

2π Ft²

Step-by-step explanation:

Concept: Area of a Semicircle = $\frac{\pi r^2}{2}$ units²

Solution: Given diameter = 4 Ft

Radius = diameter/2 = 2 Ft

$Area = \frac{\pi 2^2}{2}$ = 2π Ft²
