Question

Please help me I’m so lost

Answer 1

Area of a FULL circle is founded by Pi multiplied by radius squared

But, in the figure, a semicircle is shown , so we change the formula so that it become Pi multiplied by radius squared divided by two ( because it is HALF of a circle)

We half the diameter in order to get the radius (44/2 is 22)

Pi multiplied by 22^2 divided by 2

Which is 760.27

Answer 2

Answer:

759.88 square inches

Step-by-step explanation:

$r = \frac{1}{2}d = \frac{1}{2} \times 44 = 22 \\ \\ area = \frac{1}{2} \pi \: {r}^{2} \\ area = \frac{1}{2} \times 3.14 \times 22 \times 22 \\ area = 759.88 \: square \: inches$
