VashaNatasha [74]3 years ago
8 0

Answer:

A = 400 ft²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the vertical height ) , then

A = \frac{1}{2} × 20 × 40 = 10 × 40 = 400 ft²

The area of the circle is 144π m2<br><br> What is the diameter of the circle?
Over [174]

Answer:

Step-by-step explanation:

Remember that

Area of Circle = \pi r^2

\pi  = pi \\r = radius

They told us that for this circle, the area is 144\pi  m^2

If you put it back into the formula for area of a circle we get:

Area of Circle = \pi r^2

144\pi = \pi r^2

Divide both sides by \pi.

144 = r^2

Now we want to solve for r (r = radius).

You need to square root each side

\sqrt{144} = \sqrt{r^2}

12 = r

So now we know the radius, r = 12 metres

Also remember that

Diameter = 2r

So,

Diameter = 2 times 12 = 24 metres

It certainly not assumed to be true without proof. Not B
