A right cylinder has a radius of 3 and a height of 12. What is its surface area? O A. 9077 units2
B. 72 units2
O C. 10877 units
D. 457 units2

Option A, , is correct.

Step-by-step explanation:

The formula for the surface area of a cylinder is as follows:

A=

We know that the radius, r, is 3, and the height, h, is 12.

r=3

h=12

Pi will be rounded to 3.14.

Thus, applying the known values to the formula:

A=

A=226.08+56.52

A=282.6

In accord with the given options, we must determine which one has a product of around 282.6:

A.

B.

C.

D.

Therefore, option A, , is correct.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

- 70

this is the answer for you hope it
