What is the formula for finding lateral area?

makkiz [27]

you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.

Write an equation that represents a line that is parallel to y=3/4x and passes through the point (2,1).

Kisachek [45]

Insert the slope and point into point-slope form:-

y - 1 = 3/4(x - 2)
y = 3/4x - 6/4 + 1
y = 3/4x - 1/2

Find the area of the rug. DO NOT ROUND. what is the area?

Mademuasel [1]

Answer:

$\frac{198}{7} \ \text{feet}^{2}$

<h3>Step-by-step explanation:</h3>

Given:

Diameter of rug = 6 feet

To find the area of the rug, we need to use the formula "πr² or π(D/2)²"

Where:

r = radius
d = diameter

Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.

⇒ $\pi (\frac{D}{2} )^{2}$

⇒ $\pi (\frac{6}{2} )^{2}$

⇒ $\pi (3 )^{2}$

⇒ $\pi (3 )(3)$

⇒ $9\pi$

Substituting "22/7" as π:

⇒ $9(\frac{22}{7} )$

⇒ $(\frac{198}{7} )$

When finding the area of ANY shape, do not forget to include the units.

⇒ $\frac{198}{7} \ \text{feet}^{2}$
