Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

3.14(18^2) basically do that

What is the height of a triangle that has an area of 24 in.2 and a base with a length of 8 in.?

mylen [45]

Answer:⬇️⬇️⬇️⬇️

Step-by-step explanation: Area of a triangle = ½base times height⇒ A = ½bh

Given that the area is 24 and the base is 8, we would have this equation

24 = ½(8)h

24 = 4h divide both sides by 4

6 = h So the height of the triangle is 6 feet

CHECK

A = ½bh

24 = ½(8)(6)

24 = 4(6)

24 = 24√
