Ron is planning for the back-to-school rush at his store. Last year he estimated that he would need 168 notebooks, but he sold 200 notebooks. Explain how Ron can find the percent error of his estimate.

8 in. 8in.
16077 in
2.845.7 in
6.430.7 in
4019 in

Answers

Answer:

i think it is 1 or 5

Step-by-step explanation:

The required volume of the given cylinder will be 1607.7 cubic inches.

What is the volume of a cylinder?

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

Given that the radius and height of a cylinder are 8 in. and 8 in. respectively

The volume of a cylinder V = πr²h

As per the given question,

Here r = 8 in. and h = 8 in.

The of a cylinder = 3.14 × (8)² × (8)

Apply the multiplication operation,

The volume of a cylinder = 1607.7 cubic inches

Therefore, the required volume of the given cylinder will be 1607.7 cubic inches.

Answer:

the answer for number 1 is 72

Step-by-step explanation:

Assume the unknown value is 'Y'

18 = 25% x Y

18 = 25/100 x Y

Multiplying both sides by 100 and dividing both sides of the equation by 25 we will arrive at:

Y = 3 x 100/25

Y = 72%

Answer: 18 is 25 percent of 72

(Negative 6) (4) times (negative 6) (two-thirds)
(Negative 6 + 4) + (Negative 6 + two-thirds)
(Negative 6 + 4) times (negative 6 + two-thirds)

Answers

Answer:The answer is (Negative 6) (4) + (negative 6) (two-thirds)

Step-by-step explanation:

So basically, Negative 6x4= negative 24. Then you have to add Negative 6 x two-thirds. So 6 times two-thirds equal 4. So now you just add 24 and 4. And that equals 28. :)

The answer I (negative 6) (4) + (negative 6) (two-thirds)
