Answer:Lateral surface area is 847.8 centimeters^2
Step-by-step explanation:
The formula for determining the lateral surface area of a cylinder is expressed as
Lateral surface area = 2πrh
Where
r = radius of the cylinder
h = the height of the cylinder
From the information given,
r = 9 centimeters
h = 15 centimeters
π = 3.14
Lateral surface area = 2 × 3.14 × 9 × 15 = 847.8 centimeters^2
Answer:
Lateral surface area is 847.8 centimeters^2 is the correct answer.
Combine like terms
5x + 5 = 25
5x = 20
Divide by 5 to get x alone
x = 4
1/2(2.1)(3.5+5.7)
1.05(3.5+5.7)
(1.05)(9.2)
=9.66
I hope that's help.
