What is the area of the shaded region to the nearest tenth?
Aleks04 [339]

Answer:

15.1

Step-by-step explanation:

We know that the area of the circle is \pi r^{2}, but we are looking for the portion of the circle, this means we multiply it by the portion of the circle that is shaded.

Area of shaded region = \pi r^{2} (\frac{x}{360} )

where r = 4 and x = 108, the 360 comes from the fact that the total degrees around the circle is 360, so dividing the total amount of degrees by the angle will give us the portion we are looking for.

Area of shaded region = \frac{108}{360} \pi 4^{2} = 15.1

Another way to think about it is that the area of the total circle is \pi r^{2}, multiplying it by a fraction, a number less than 1, would give us a smaller value.

Hope this helps.

Find the area of EFGH
asambeis [7]

The area of triangle EFG with a base of 2 feet and height of 8 feet is 8 ft².

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of triangle ABC, hence:

18 ft² = (1/2) * 3 * h

h = 12 ft

Let x represent the height of triangle EFG, hence:

x/12 = 2/3

x = 8 feet

Area of EFG = (1/2) * 2 * 8 = 8 ft²

The area of triangle EFG with a base of 2 feet and height of 8 feet is 8 ft².

gulaghasi [49]
$$\begin{matrix}&#10;V\\\\=\pi r^2\left(\frac{h}{3}\right)\\\\=\pi \left(5\right)^2\left(\frac{15}{3}\right)\\\\=25\pi \left(5\right)\\\\=125\pi \\\\\approx 392.69908\\\\\approx \mathbf{392.7\:units^3}&#10;\end{matrix}$$
