First the 2 bases have surface area pi*1.25^2*2
Then the side
2.5pi*4=10pi
total of 9.817+31.415
=41.232
This approximation could be further round down for this problem to 41.2
Which makes choice C the correct choice.

Answer:
33
Step-by-step explanation:
a right angle is 90 degress since the other side is 57 than ac must be 33
Answer:
x=9
Step-by-step explanation:
a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.
15/5 = 3
12/4 = 3
therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.
3*3=9
x=9
Answer:
y = 41
Step-by-step explanation:
When you add 41 and 4, you would get 45.
When you divide by 5, it will be equal to 9:
45 ÷ 5 = 9
