If a cone-shaped vase can hold 45 cubic centimeters of water and has a radius of 2 centimeters, what is the height of the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answers

Answer 1

Answer:

Answer:

3.58

Step-by-step explanation:

45cm3= 2 squared x height x 3.14

So you take 45 and divide it by 2 squared which is 4 and 3.14. Then you would get 3.582 and round it to 3.58

Answer 2

Answer:

Answer:

13.14

Step-by-step explanation:

v= 1/3 pi r^2 h

45 = 1/3 (3.14) (4) h

45 = 1/3 (12.56) h

45 = 1/3 12.56/ 4 = 4 h/4

h = 3.14

45 = 1/3 (12.56) (3.14)

45 = 1/3 (39.44)

45 = 39.44/3 = 13.14

Can you help me with this other question please?A frozen yogurt shop offers scoops in cake cones, waffle cones, or cups. You can get vanilla, chocolate, strawberry, pistachio, or coffee flavored frozen yogurt. If you order a single scoop, how many outcomes are in the sample space? I didn't really understand it.

Answers

There is 4 outcomes per cone/cups so therefore the answer 4*3 which equals 12.

I think if you got 1 scoop, then there would be 7 possible outcomes. I hope this helps!

Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 5 yards of fabric, plus 20% extra fabric. Derek bought 3 yards of fabric, plus 25% extra. Who bought more fabric? How much more?

Answers

Answer:

Jessica bought 2.25 yards more material than Derek.

Step-by-step explanation:

Jessica bought 5 yards of fabric.

20% extra fabric = 20% of 5

= (20×5)/100

= 1 yard

Total fabric bought by Jessica = 5+1 = 6 yards

Derek bought 3 yards of fabric.

20% extra fabric = 25% of

= (25×3)/100

= 0.75 yard

Total fabric bought by Derek = 3 + 0.75 = 3.75 yards

So,

Difference = 6 - 3.75 = 2.25 yards

Answer: Jessica bought 2.25 yards more material than Derek.

20% = 0.2
(5 * 0.2) + 5
5 * 0.2 = 1
5 + 1 = 6

25% = 0.25
(3 * 0.25) + 3
3 * 0.25 = 0.75
3 + 0.75 = 3.75

6 - 3.75 = 2.25

Jessica bought 2.25 yards more material than Derek.
