Answer:

Diameter=22 inches

Step-by-step explanation:

It is given that The area of a circle is approximately 379.94 square inches, then using the formula for the area of the circle, we get

A={\pi}r^2

Substituting the given values, we have

379.94={\pi}r^2

⇒379.94=3.14r^2

⇒\frac{379.94}{3.14}=r^2

⇒r^2=121

⇒r=11

Now, the diameter of the circle is given as:

D=2r

Putting the value of r, we have

D=2(11)

⇒D=22 inches

Thus, the diameter of the circle is 22 inches.

What is the area of the triangle?
Luda [366]

Answer:

270cm^2

Step-by-step explanation:

The side length is irrelevant and does not matter.

The area of a triangle is found by multiplying the base by the height and then dividing that by two.

For this problem it would be...

30*18=540

540/2=270

So the area would be 270cm^2
