Step-by-step explanation:
Πr^2(h)
π(1.2)^2)(4)=18.1 ft^3
22*18.1=398.2
Answer:
4
Step-by-step explanation:
It’s a right triangle.


100+x^2=4(29)
16=x^2
x=4

I had this question a few minutes ago, that’s funny
Answer:
10
β
Step-by-step explanation:
We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10
β
on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10
β
.
You can also use double angle formulas from the previous step:
(sin(2β) = 2 sin(β) cos(β))and find that:
5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =
10
β
cos(β)
But since cos(β) is already present, we can see that the answer is 10
β
