Answer:
The height of the another cylinder 'h' = 7
Step-by-step explanation:
<u>Explanation</u>:-
<u>Step 1:-</u>
Surface area of the cylinder = 2пrh + 2пr^2
Given radius of first cylinder is 20cm
given height of the first cylinder is 2 cm
The surface area of first cylinder is = 2пrh + 2пr^2
= 2п(20)(2)+2п(2)^2
= 4п(20+2)
The surface area of first cylinder is 88п
<u>Step 2</u>:
given data The surface area of first cylinder is 88п is same as second cylinder also
<u>Find the height of the second cylinder</u>
Given Radius of the second cylinder r = 4
Surface area of the cylinder = 2пrh + 2пr^2 = 88п
2п(4)h+2п(4)^2 =88п
on simplification we get
2п (4h+16) = 88п
after cancellation '2п' value and on simplification, we get
4h+16 = 44
4h = 44-16
4h = 28
h=7
Therefore the height of the another cylinder is 'h' =7
Lateral area is area of 3 rectangles
Rectangle 1 a 2 sides 4 and 6, so 4x6= 24
Rectangle 2 a 2 sides 6 and 8, so 6x8=48
Rectangle 3 a 2 side 4 and 8, so 4x8=32
And we have 24+48+32= 104

Step-by-step explanation:
Answer:
1: 2
2: 5
3: 8
4: 11
5: 14
Step-by-step explanation:
To get the table values, plug the x values into the function.
3(1)-1 = 2
3(2)-1 = 5
3(3)-1 = 8
3(4)-1 = 11
3(5)-1=14
