Area inside the semi-circle and outside the triangle is (91.125π - 120) in²

Solution:

Base of the triangle = 10 in

Height of the triangle = 24 in

Area of the triangle = $\frac{1}{2} bh$

$$=\frac{1}{2} \times 10\times24$

Area of the triangle = 120 in²

Using Pythagoras theorem,

$\text{Hypotenuse}^2=\text{base}^2+\text{height}^2$

$\text{Hypotenuse}^2=10^2+24^2$

$\text{Hypotenuse}^2=100+576$

$\text{Hypotenuse}^2=676$

Taking square root on both sides, we get

Hypotenuse = 23 inch = diameter

Radius = 23 ÷ 2 = 11.5 in

Area of the semi-circle = $\frac{1}{2}\pi r^2$

$$=\frac{1}{2} \pi \times (13.5)^2$

Area of the semi-circle = 91.125π in²

Area of the shaded portion = (91.125π - 120) in²

Area inside the semi-circle and outside the triangle is (91.125π - 120) in².

One batch of trail mix uses 2 cups of cereal, 1/4

Elenna [48]

To make 3 batches of trail mix you need 6 cups of cereal, 3/4 cup of raisins and 2 cups of almonds, while to make 4 batches you need 8 cups of cereal, 1 cup of raisins and 2 and 2/3 cups of almonds.

<h3><u>Fractions</u></h3>

Since one batch of trail mix uses 2 cups of cereal, 1/4 cup of raisins, and 2/3 cup of almonds, to determine how much of each ingredient you would need to make 3 or 4 batches of trail mix, the following calculation must be performed:

3 batches =
2 x 3 = 6
1/4 x 3 = 3/4
2/3 x 3 = 0.666 x 3 = 2

4 batches =
2 x 4 = 8
1/4 x 4 = 1
2/3 x 4 = 2 2/3

So to make 3 batches of trail mix you need 6 cups of cereal, 3/4 cup of raisins and 2 cups of almonds, while to make 4 batches you need 8 cups of cereal, 1 cup of raisins and 2 and 2/3 cups of almonds.
