Find the surface are of the cylinder in terms of pi
Andrej [43]
Hello!

To find the surface area of a cylinder you use the equation

SA = 2 \pi rh + 2 \pi  r^{2}

SA is surface area
r is radius
h is height

PUt in the values you know

SA = 2 \pi (7)(18) + 2 \pi  * 7^{2}

Square the number

SA = 2 \pi (7)(18) + 2 \pi * 49

Multiply 7 and 18

SA = 2 \pi * 126 + 2 \pi  * 49

Multiply 126 by 2

SA = 252 \pi  + 2 \pi  * 49

Multiply the 49 by 2

SA = 252 \pi  + 98 \pi

Add

SA = 350 \pi

The answer is A)350 \pi cm^{2}

Hope this helps!

Answer:

Concept: Mathematics

When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.

  1. 1.365 × 10^1
  2. You see its positive 1 hence we move one space to the right
  3. Our answer is now 13.65

You keep doing the same thing

  1. 1.365 × 10^2
  2. 136.5

Lastly

  1. 1.365 ×10^3
  2. 1365
