Question

6. find the area of a semicircle whose radius is 2.4 cm?​

Answer 1

Answer:

15.072

Step-by-step explanation:

The radius of a circle is half of a diameter so double that and to find the area of a circle you multiply the diameter by 3.14

Answer 2

The required area of the semicircle whose radius is 2.4 cm is 9.0432 cm^2

What is area of semicircle?

The area of the semicircle is half of the area of the circle.

If circle having radius r, then the area of the circle is $\pi r^2$

So the area of the semicircle is $\frac{1}{2}.\pi r^2$

How to calculate area of the semicircle?

Here we have given that the radius r = 2.4 cm

Now putting the value of r into above formula

Area of semicircle  = $\frac{1}{2}.(3.14).(2.4)^2$

Area of semicircle = $1.57(5.76)$

Area of semicircle = 9.0432 cm^2

The required area is 9.0432 cm^2

This is the conclusion to the answer.
