A semicircular flower bed has a diameter of 3 metres.

What is the area of the flower bed?

m2


Give your answer to 1 decimal place.



Area of circle = πr²


Use π = 3.14


You can use a calculator for this question.

Verified Answer :

7.065 
A semi circular shape is referring to half a circle.
We have the formula for the area of a circle so plug in the #.
r which is radius is equal to half the diameter and for pi we use 3.14

(3.14)(1.5)^2
Using a calc we get 7.065 
since it says one decimal place we round it to 7.1 since the next digit 6 is greater than 5

Answer:

\(3.5\ m^{2}\)

Step-by-step explanation:

we know that

The area of a circle is equal to

\(A=\pi r^{2}\)

so

The area of a semicircle is equal to

\(A=\frac{1}{2} \pi r^{2}\)

In this problem we have

\(r=3/2=1.5\ m\) -----> the radius is equal to the diameter divided by two

\(\pi=3.14\)

substitute in the formula of area of the semicircle

\(A=\frac{1}{2}*(3.14)*(1.5^{2})=3.5\ m^{2}\)
