First you need to find the radius. To do that you need to divide the diameter by two;
45 / 2 = 22.5
Then you plug the radius in the formula for a sphere. Which is...
V = (4 / 3)πr^3
First you need to find the volume with out pi
V = (4/3) π (45)^3
V= π (4/3) (91,125)
Your answer with out pi is...
V= (68,343.75) π cm^3
And with pi is...
V = 214,708.22 cm^3
He should increase the length and width by a factor = sqrt 3.
so new length should be 78* sqrt3 = 135.1 - that is increase of 58.1 ft
and new width should be 65 * sqrt3 = 112,58 = increase of 47.58 ft
Answer:
D
Step-by-step explanation:
16x-8x-12=24+20
Combine like terms.
8x -12 = 44
Add 12.
8x = 56
Divide by 8.
x = 7
That's your answer!
Answer:
k - 3 : k + 2
Step-by-step explanation:
3 less than k = k - 3
2 more than k = k + 2
Ratio of 3 less than k to 2 more than k
In ratios, the word 'to' is represented as a colon :
k - 3 : k + 2
Hope this helps :)
