Hollow spheres with a radius of 8 cm whose shell is 2.5 cm thick. About how much chocolate will go into making wash sphere?

About chocolate will go into making wash sphere .

Step-by-step explanation:

Here we have , Hollow spheres with a radius of 8 cm whose shell is 2.5 cm thick.  We need to find  About how much chocolate will go into making wash sphere .Let's find out:

Basically we need to find the volume of hollow sphere , We know that volume of hollow sphere is :

⇒            .............(1)

According to question ,

Putting these values in equation (1) :

⇒

⇒

⇒

⇒

Therefore , About chocolate will go into making wash sphere .

2080 cm³ (correct to 3sf)

Step-by-step explanation:

Volume = (4/3) × 3.14 × [8³ - 2.5³]

= 2078.156667 cm³

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

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

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
