Create 3-D models of a cone and a cylinder. You can start out by using an empty can, a toilet paper tube, or a snow cone holder.

(Just make sure they are clean and dry.) The height of the cone and the radius of the base of the cone must be equal to the height of the cylinder and the radius of the base of the cylinder. If you cannot find two existing items that match these requirements, you can make one or both of the items yourself. Now, once you have your cone and your cylinder, fill the cone completely with sand, small pebbles, peanuts, or any other substance that your model can hold. Transfer the cone's contents to the cylinder, refilling the cone after each transfer. Do this as many times as it takes to completely fill the cylinder.
A. How many times were you able to transfer the contents of the cone into the cylinder?

??is that namjoon i cant really see the profile picture you have lol ??

Answer:

V cone = pi• radius ^2 • height/ 3  

V cylinder= pi• radius ^2. • height  

1) three times cone is smaller then cylinder that have the same radius and height

3. A children's slide is 10 feet long and inclines 64° from the ground. The
Nata [24]

Answer:

  87.0°

Step-by-step explanation:

The law of sines can be used to solve this. We have two sides of a triangle and the angle opposite one of them. We want to find the angle opposite the other known side.

In the attached, the triangle is ΔACS. We have side "a" = 9, and side "c" = 10. Angle A is given as 64°. The law of sines tells us ...

  sin(C)/c = sin(A)/a

  sin(C) = (c/a)sin(A)

  C = arcsin((c/a)sin(A)) = arcsin(10/9·sin(64°)) ≈ 87.03°

The ladder makes an angle of about 87° with the ground.

After arianna completed some work, she figured she still had 78 21/100 pictures to paint. if she completed another 34 23/25 pict
dezoksy [38]

Subtract the number she completed from what she had left to paint originally.

The fractions have different denominators so first step is to rewrite the fractions with a common denominator.

23/25 can be rewritten as 92/100

Now you have 78 21/100 - 34 92/100

Because 21/100 is smaller than 92/100 subtract 1 whole number from 78 and rewrite 1 as 100/100 and add that to the fraction.

78 21/100 becomes 77 121/100

Now subtract :

77 121/100 - 34 92/100

77-34 = 43

And 121/100 - 92/100 = 29/100

Combine to get 43 and 29/100

Tom Thomas took tennis lessons. He traveled 12 miles one way at an average cost of $0.42 per mile. His racket cost $94, balls co
Furkat [3]
Racket : 94
balls : 12.50
warm ups : 34
shorts : 19.95
shoes : 44.50
total with tax : 204.95 + .05(204.95) = 204.95 + 10.25 = 215.20

20 per lesson for 12 lessons : 20 * 12 = 240
12 miles 1 way....thats 24 miles round trip, at 0.42 per mile : 24(0.42) = 
10.08.....lessons and mileage : 240 + 10.08 = 250.08

for a total of : 215.20 + 250.08 = 465.28 <==
