You decide to make a beanbag in the shape of a sphere with a diameter of 120 millimeters. You will need to find the volume to know how many beans to put in the bag. What is the volume? Use 3.14 to approximate pi.

Answers

Answer:

The volume is $904,320\ mm^(3)$

Step-by-step explanation:

we know that

The volume of the sphere is equal to

$V=(4)/(3)\pi r^(3)$

we have

$r=120/2=60\ mm$ ----> the radius is half the diameter

$\pi=3.14$

substitute the values

$V=(4)/(3)(3.14)(60)^(3)=904,320\ mm^(3)$

Is 8 yd greater than 288 in.

Answers

3 feet is equal to 1 yard and 3 feet is 36 inches. 288 inches divided by 36 is 8 so 8 yards is equal to 288 inches.

I believe they are the same since one yard is 36 in, so 8x36 is 288. Hope i helped :)

Start by calculating minutes until 4:00. So, from 3:16 to 3:20, there is 4 minutes, then from 3:20 to 4:00 there is 40 minutes. 44 minutes total. Then, from 4:00 to 6:00 there is 2 hours. The total time he is at the party is 2 hours and 44 minutes.

What is the slope of the line that passes through the pair of points (-10,14) and (-6,12).

Answers

Answer:

Step-by-step explanation:

(-10,14) and (-6,12)

y2 = 12, y1 = 14, x2 = -6, x1 = -10

Slope m = (y2 - y1)/(x2 - x1)

m = (12 - 14)/(-6 + 10)

m = -2/4

m = -1/2

The equation of line

y - y1 = m(x - x1)

y - 14 = -1/2(x + 10)

y - 14 = -x/2 - 5

y = -x/2 - 5 + 14

y = -x/2 + 9

Zack divides 6 cups of fruits juice equally among 8 friends how much does each friend get?

Answers

number of cups you have / number of friends to share it between = 6/8

You can simplify 6/8 by dividing both the numerator and the denominator by 2.

6/8 = 3/4 or 0.75 of a cup
