Find the measures of the interior angles.<br><br><br><br><br><br><br> what is angle A, B, and C
lina2011 [118]

Answer:

75 degrees.

Step-by-step explanation:

All interior angles of a triangle add up to 180.

So we can set up an equation: 65+40+x=180

The volume of cylinder is 448 pie cm cube and height 7 cm find its radius<br>​
Verizon [17]

<u>Answer:</u>

r =\bf 8 \space\ cm

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

The formula for volume of a cylinder is as follows:

\boxed{Volume = \pi r^2 h}

where:

• r = radius (? cm)

• h = height (7 cm).

Substituting the values into the formula:
448 \pi  = \pi \times r^2 \times 7

Now solve for r:

⇒ r^2 = \frac{448 \pi }{\pi \times 7}

⇒ r = \sqrt{64}

⇒ r =\bf 8 \space\ cm
