How do you find the surface area and volume of a cylinder ​
galina1969 [7]
<h2>Answer:</h2>

The surface area of a shape is the sum of the area of all of its faces. To find the area of a cylinder, you need to find the area of its bases and add that to the area of its outer wall. The formula for finding the area of a cylinder is A = 2πr2 + 2πrh.

<h2>Step-by-step explanation:</h2>
  • Surface area of a cylinder = 2πr 2 + 2πrh
  • Volume of a cylinder = πr 2 h
  • You need to know the radius and height to figure both the volume and surface area of a cylinder.
  • Answers for volume problems should always be in cubic units.
  • Answers for surface area problems should always be in square units.

If the length of segment AC equals 58, what is the length of the midsegment DE
Delicious77 [7]

Answer:

B) 29

Step-by-step explanation:

Given:

AC= 58

Point D and E are the midpoints of side AB and BC Respectively.

Solution:

According to Midpoint theorem which states:

"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."

\therefore DE= \frac{1}{2} AC

DE= \frac{58}{2} =29

Hence length of DE is 29.
