The radius of a semicircle is 3 feet. What is the semicircle's area?<br>Use 3.14 for Pi​
valentinak56 [21]

Answer:

14.13 ft²

Step-by-step explanation:

The area of a semicircle is

=  \frac{\pi \:  {r}^{2} }{2}

We were given the radius of the semicircle to be: r=3 feet.

We were also asked to use π as 3.14.

We substitute into the formula to get:

=  \frac{3.14 \times  {3}^{2} }{2}

This is the same as:

=  \frac{3.14 \times  9}{2}

Or

= 3.14 \times  4.5

= 14 .13 {ft}^{2}

The area of the semicircle is 14.13 ft²
