To clarify, there is a hole where the bottom of the small cylinder would be, and that hole is also present in the top of the big cylinder. In other words, there is only one base in the small cylinder, and the top base of the big cylinder has a hole cut in it.

Answer 1
Answer: surface area is defined as the sum of all the areas covers the object so here we have 2 cylinders and the
Area of a cylinder = side area + area of the circle 
side area perimeter * height = 2*pi* r *h
area of the circle = pi * r^2 
for the cylinder, we have 2 area circle and 1 side area 
so surface area = 2 *pi * r*h + 2 pi* r^2 
so for the first cylinder 
A1 = 2*pi*r*h +2 pi * r^2 = (2*pi * 2 *2) +( 2 *pi * 2^2 ) = 16pi inch^2 
A2 = 2*pi*r*h + 2pi *r^2 = ( 2 * pi * 1.25*3)+( 2*pi *(1.25)^2) = 85/8 pi inch^2 
A= A1 +A2 
A = 16pi + 85/8 pi = 83.645 inch^2

Solve for x.31 = 3x - 14. Simplify as much as possible. THanks =) :)

Answers

Answer:

x =  15

Step-by-step explanation:

Given in the question an equation

31 = 3x - 14

Solution

rearrange the constant to the right of equation

3x = 14 + 31

3x = 45

divide 3 on both sides of the equation

3x/3 = 45/3

      x = 15

Answer:

x=15

Step-by-step explanation:

The given equation is;

31=3x-14

Group similar terms:

31+14=3x

Combine the left hand side to obtain;

45=3x

Divide both sides by 3 to get;

x=(45)/(3)

x=15

Regina purchased 1.8 pounds of turkey breast from her local deli for $5.99 per pound. To the nearest cent, how much did she spend in all?

Answers

Answer:

Step-by-step explanation:

  • Step 1: Find the total amount spent.

Number of pounds purchased = 1.8 pounds

Cost per pound = $5.99

⇒ Total amount spent = 5.99 × 1.8 = $10.782

  • Step 2: Convert to cents

10.782 × 100 = 1078.2 cents

1.8 x 5.99 = 10.782

10.782 rounded to the nearest hundredth is 10.78

so the answer is 10.78

Elliott's bed is 75 inches long. During his growth spurt, Elliott grew 6 inches. Before his growth spurt, he was 5 feet 11 inches tall. How much shorter is Elliott's bed than Elliott?

Answers

Firstly, you need to convert 75 inches into feet and inches. 75 inches in feet and inches is 6ft 3 inches.
Elliot was 5ft 11 then grew 5 inches.
There is 12 inches in a foot, meaning he will become 6ft 4. 
You've then got to subtract 6ft 3 from 6ft 4, and this leaves you with 1 inch.
Therefore, Elliott's bed is 1 inch shorter than him.
Hope this helps :) 

Answer:

1 inch
