The volume of a CONE-shaped hole is 75pi ft cubed. If the hole is 9 feet deep, what is the radius of the hole?
Arturiano [62]

Answer:

The radius of hole is 5 feet

Step-by-step explanation:

Depth of conical hole = 9 feet

Let the radius of hole be r

Volume of conical hole =\frac{1}{3} \pi r^2 h

So, Volume of conical hole =\frac{1}{3} \pi \times r^2 \times 9

We are given that volume of a CONE-shaped hole is 75pi ft cubed.

So,\frac{1}{3} \pi \times r^2 \times 9=75 \pi

\frac{1}{3} \times r^2 \times 9=75

r^2=\frac{75 \times 3}{9}

r=\sqrt{\frac{75 \times 3}{9}}

r=5

Hence The radius of hole is 5 feet

Find the missing angle measure. then classify the triangle by its angles and by its sides.
iren [92.7K]

Answer:

Part a) The measure of the missing angle is 90\°

Part b) The triangle of the figure is a right triangle

Part c) The triangle of the figure is a scalene triangle

Step-by-step explanation:

we know that

The sum of the interior angles of a triangle is equal to 180\°

so

Let

x------> the missing angle

we know that

x\°+50\°+40\°=180\°

solve for x

x=180\°-90\°=90\°

The triangle of the figure is a right triangle --------> by its angles

Because the triangle has an angle measure of 90\°

The triangle of the figure is a scalene triangle --------> by its sides

Because the three angles and the three sides measures are different
