<u>Answer-</u>
<u>Solution-</u>
The dimensions of the cuboid is, 80×80×140 cm
So, its volume will be 
cm³
The dimensions of the cylinder is, radius = 40cm, height = 70cm
So, its volume will be 
cm³
Total volume,
As we know,
Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° = 
, then
tanf° = 
= 
= 
= ( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
Answer:
On average, the project takes 4 weeks to complete.
Step-by-step explanation:
We have these following probabilities:
25% probability that the activity takes 2 weeks.
50% probability that the activity takes 4 weeks.
25% probability that the activity takes 6 weeks.
How long does the project now take to complete (on average)
We multiply each duration by it's probability.
0.25*2 + 0.5*4 + 0.25*6 = 4
On average, the project takes 4 weeks to complete.
Volume of sphere is 4/3* pi*r^3
r is half of diameter. So 5.25 in this case
Plug It in.
Becomes ~606.13
