Answer:
The answer to your question is 9923 cm²
Step-by-step explanation:
Data
radius = 30.8 cm
height = 20.5 cm
Surface area = ?
Process
1.- Write the formula to calculate the surface area of a cylinder
SA = 2πr² + 2πrh
2.- Substitution
π = 3.14
SA = 2(3.14)(30.8)² + 2(3.14)(30.8)(20.5)
3.- Simplification
SA = 5957.459 + 3965.192
4.- Result
SA = 9922.65 cm² or SA = 9923 cm²
It’s D that is the answer
3/4+-2 1/9=your ****ing answer
Answer is 80pi
Step by step
To find lateral_area = (2 * π * r) * h
Since it’s in term of pi,
(2 x radius x height) pi
2 x 4 x 6 = 48pi
base_area = 2 * π * r²
Since it’s in terms of pi
(2 x r^2)
(2 x 4^2)
= 32pi
Total surface area in terms of pi = 32+48
= 80pi
You find a triangle with two of the points. Use rise over run (up or down and left or right) See how many squares rise takes and how many squares run takes. Then with rise/run simplfy the fraction and you should get the slope.
