Answer:
I thinks its T (3)
Step-by-step explanation:
Answer:
x = 
Step-by-step explanation:
given
cos(x -
) = - 1, then
x -
=
(- 1) = π
Add
to both sides, hence
x = π +
= 
Answer:
I think its D but I'm not sure. I think you're right.
Step-by-step explanation:
Answer:
x = y − 6 Is your answer
Step-by-step explanation:
y = x + 6
x = y -6
Formula: V = (2/3) π r 3.
Radius is 3cm.
So, now we can plug it in to solve for the volume.
V = (2/3) π 3^3
First, let's multiply 3^3.
3^3 = 27
Then, 27 x π = 84.82
After, multiply by 2/3.
84.82 x 2/3 = 56.55
Lastly, round 56.55 to the nearest tenth of a cubic centimeter.
56.55 = 56.6
Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.
