The volume of the original cylinder is
... V = π·r²·h
For r=1 and h=1, this is
... V = π·1²·1 = π
For the new cylinder, the volume is 1.089 times that amount.
... V = 1.089π = π·1.1²·(1-k)
... 1.089/1.21 = 1-k
... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%
The appropriate choice is (B) 10.
The drop down menu is 561, 1268, 1760, and 2354
Answer:
5, 0.55, 2.00, 3 cm.
Step-by-step explanation:
If you're asking about the unit rates, then..
a. For 1 day, there is 5 mm of rain. 15 / 3 = 5
b. One chocolate bar costs $0.55. 2.20 / 4 = $0.55
c. $14.00 / 7 = 2.00 Indu saves $2.00 for one day.
d. 12 / 4 = 3 cm. For one month, philip grew 3 cm.
I hope this helped :)
