Surface area of cylinder = 2 x pi x r x h + 2 x pi x r*2
So 2 x pi x 4 x 11 + 2 x pi x 4*2 = 376.99

Answer:
Step-by-step explanation:
There are 3 blue, 5 red and the total of 8 marbles.
<u>Two different colored marbles are:</u>
- blue, then red or red, then blue
<u>Find the probability of each case:</u>
- P(b, r) = 3/8*5/7 = 15/56
- P(r, b) = 5/8*3/7 = 15/56
<u>Required probability is:</u>
- P(different color) = 15/56*2 = 15/28
Answer:
The graph is symmetric. The mean and median are about equal in a symmetric graph. The median is shown as 109, so the mean is approximately 109.
Step-by-step explanation:
The graph is symmetric.
Because the graph is symmetric, the mean and median should be approximately equal.
According to the graph, the median is 109. Therefore, the mean is approximately 109.
