A cylindrical pop can us 12.5 cenimeters tall and 5.5 centimeters wide. what is the volume of the pop can

Answers

Answer 1
Answer: The width is basically the diameter:
Given 
Diameter = 5.5 cm
So Radius = (d)/(2)(5.5)/(2) = 2.75 cm
Height of cylinder = 12.5 cm

Formula of the volume of a cylinder
V = Area of base × height of prism
    = \pir² × h
    =(2.75)² (\pi) × 12.5
    =7.5625\pi × 12.5
    ≈ 296.83 cm³

Divide 2 1/2 by 1 5/8=

Answers

1) Convert the mixed numbers into improper fractions (ex. 2 1/3 ÷ 4 1/2= 7/3 ÷9/2)
2) Find the reciprocal of the SECOND number. Then change the division sign to a multiplication sign. (ex. 7/3 ÷ 9/2=7/3×2/9) 
3)Multiply and you've got your answer! (ex. 7/3×2/9=14/27)

How does one solve this question, any help would be appreciated! I feel this has a really easy solution and I've decided to significantly over-complicate it.13. a) Write down the equation of the line with gradient 3 passing through (0, -2)

b) Write down the equation of the line which is parallel to the line y=4-5x passing through (0,-1)

Answers

Hello,

a)
the gradient is the slope:

y+2=3(x-0) or y=3x-2

b) slope is -5 (parallele to y=-5x+4)

y+1=-5(x-0) or y=-5x-1

If one honeybee makes 1/12 teaspoon of honey during its lifetime, how many honeybees are needed to make 1/2 teaspoon of honey

Answers

In this case we have to have a common denominator in order to compare to the two fractions.
(1)/(2) =  (x)/(12) We know that 2 × 6= 12 
So multiply the numerator and denominator by 6
(1)/(2) × (6)/(6) =  (6)/(12)
Therefore, the amount of honey needed is (6)/(12) teaspoons
So in total 6 bees are needed to make (1)/(2) teaspoons of honey because we know that (6)/(12) is the same as half

anthony made 6 bouquets.if he used 3/4 of a bunch of flowers for each bouquet how many flower bunches did he need

Answers

So first you have to times 6 and 3/4 
to do that you have to make a equation like 6/1*3/4=? 
So next you multiply six and three to get 6/1*3/4=18/?
then multiply the bottom one and four to get 6/1*3/4=18/4
then simplfy to get 4 2/4 but you can't have half a bouquet of flowers so you round up to five 

He needed 4 1/2 bunches So 5 bunches
