Hey there :) You'll have to use the formula of cylinder to get your answer :
Surface area of cylinder : 2(pi)(r^2) + 2(pi)(r)(h)
pi = 22.7 or 22/7
r (radius of cylinder) = 8 mm
h = height of cylinder = 20mm
●Hence, just substitute your answer in the given formula and also don't forget to check whether the answer required needs to be in mm or cm.
Hope it helps :)
Answer:
12 rides
Step-by-step explanation:
First, get the total and subtract it from the expenses.
34 - 8.50 - 4.50 = 21
Then divide the answer by how much each ride costs to find the answer
21 ➗1.75 = 12
So Sam can ride 12 rides.

3,723 Your answer is: 3,723
So we replace x with 3. f(3)=3^2-2(3)+6. and f(3)=9-6+6=9. and the answer is d which is 9.
<u>Given:</u><u>-</u><u> </u>
- Height of Cylinder = 21ft.
- Radius of Cylinder = 7ft.
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
- Formula for finding surface area of Cylinder = 2πr(r+h)
<u>Putting</u><u> the</u><u> known</u><u> values</u><u> </u><u>,</u><u> </u>
<u>Surface</u><u> Area</u><u> </u><u>=</u><u> </u>2×3.14×7(7+21) ft.²
= <u>1230.88 ft</u>.²
