Answer:
B
Step-by-step explanation:
Surface area of a cylinder = 2πrh+2πrsquared
= 2x3.14x4.5x12+2x3.14x20.25
= 339.12+127.17
= 466.29
Therefore, the surface area of a cylinder is 466.29cm
M = C*(1+i)^t
M = 1000*(1+0,05)¹
M = 1000*1,05
M = 1050 (earns $ 50)
se t = 2 meses:
M = 1000*(1+0,05)²
M = 1000*(1,005)²
M = 1.102,50

Answer -
(In miles)
EXPLANATION
We know that distance traveled is calculated by multiplying average speed by total time.
According to the table,
Uphill average speed =
(in miles per minute)
Uphill travel time = x (in minutes)
Total distance uphill =
(In miles)
The same way,
Downhill average speed =
(in miles per minute)
Downhill travel time = 42 - x
Total distance downhill = Speed * Time =
(In miles)
