Answer:

7038  square inches

Step-by-step explanation:

Formula for Surface area is given by = 2\pi r h + 2\pi r^2

             here radius (r) = 14 inches

                     height (h) = 66 inches

   Surface area = 2\pi (14) (66) + 2\pi (14)^2

                         = 5806+2(616)

                          = 5806+1232

                          = 7038 square inches

What are the restrictions on the domain (u*v)(x)
Zepler [3.9K]

Answer: x≠0 and x can not be any value for which u(x) = 2

Step-by-step explanation:

According to the question,

The domain of the function u = R - {0}

Thus if x is the element of the domain of the function u

Then , x ≠0

(v*u)(x) = v[u(x)]

Since, The domain of the function v = R - {2}

⇒ u(x) ≠ 2

⇒ Second Option is correct.

christian has $425.82 in his checking account . How much does he have in his account after he makes a deposit if 120.75 and with
Oksanka [162]
A deposit adds to the amount of a checking account.
So a deposit of $120.75 is + 120.75.
A withdraw subtracts from the amount of a checking account.
So a withdraw of $185.90 is - 185.90.

If the original amount is $425.82, you would simply add the amount of the deposit then subtract the amount of the withdraw.

425.82 + 120.75 - 185.90 = 360.67

So the amount in Christian's checking account after <span>a deposit if $120.75 and withdrawal of $185.90 is $360.67.

Answer:
$360.67

Hope this helps! :)

244 times 21/61 times 5/8
scoundrel [369]
The answer is 52.5 because you are suppose to multiply each number in pairs. First multiply 21/61 times 5/8.Then you will get 105/488. Multiply 105/488 times 244/1 which equals 25,620/488. Simplify to the lowest form which equals 6,405/122. Divide 6,405 divided by 122. The answer will be 52.5. That is how you will get the answer.
