The volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

<h3>What is a sphere?</h3>

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

We know the surface area of the sphere is given by:

SA = 4πr²

1465 = 4πr²

r = 10.79 cm

Volume of the sphere = 4πr³/3

V = 4π(10.79)³/3

V = 5262.03 cubic cm

Volume of five volleyballs = 5×5262.03 = 26310.15 cubic cm

Thus, the volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide 3 on both sides:                    x < 13

Here we see that any value <em>x</em> smaller than 13 would work as solution to the inequality.

Ben and Joel are raising money for their class trip by selling wrapping paper. Ben raised $43.50 by selling 12 rolls of solid pa
enyata [817]

Answer:

Solid paper costs 1.75 each

Printed paper costs 2.50 each

Step-by-step explanation:

Given:

Ben = $43.50 (12 rolls solid paper and 9 rolls of printed paper)

Joel = $51.50 (8 rolls solid paper and 15 rolls of printed paper)

Let x = solid paper

Let y = printed paper

12x + 9y = 43.50

 8x + 15y = 51.50

Find x:

8x + 15y = 51.50

8x = 51.50 - 15y

x = (51.50 - 15y)/8

Substitute x:

12x + 9y = 43.50

12(51.50 - 15y)/8 + 9y = 43.50

(618 - 180y)/8 + 9y = 43.50

8 (618 - 180y)/8 + 8*9y = 43.50 * 8

618 - 180y + 72y = 348

-108y = 348 - 618

-108y = -270

-108y/-108 = -270/-108

y = 2.50

x = (51.50 - 15y)/8

x = (51.50 - 15(2.5) /8

x = (51.50 - 37.50)/8

x = 14/8

x = 1.75

To check: x = 1.75 ; y = 2.5

12x + 9y = 43.50

12(1.75) + 9(2.5) = 43.50

21 + 22.50 = 43.50

43.50 = 43.50

8x + 15y = 51.50

8(1.75) + 15(2.5) = 51.50

14 + 37.50 = 51.50

51.50 = 51.50

Micheal has a set of 5 cards shown below. Micheal wil randomly select a card, not replace it, then select another card. What is
strojnjashka [21]

Answer:

3/20 or 15%

Step-by-step explanation:

Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.

To find the probability you need to multiply the two probabilities together.

3/5 times 1/4 is 3/20.

So your answer is 3/20 or 15%.

I NEED HELP PLSSS , what is the volume and surface area
GaryK [48]

Given:

The dimensions of the given cuboid are 8 in, 6 in and 7 in.

To find:

The volume and the surface area of the given cuboid.

Solution:

The volume of cuboid is:

V=l\times b\times h

Where, l is length, b is breadth and h is height.

V=8\times 6\times 7

V=336

Therefore, the volume of the cuboid is 336 cubic inches.

The surface area of the cuboid is:

A=2(lb+bh+hl)

Where, l is length, b is breadth and h is height.

A=2(8\times 6+6\times 7+7\times 8)

A=2(48+42+56)

A=2(146)

A=292

Therefore, the surface area of the cuboid is 292 square inches.
