The law of cosines :
A^2 = B^2 + C^2 - 2BC cos A
2^2 = 3^2 + 4^2 - 2 . 3. 4 cos theta
= 21

The area of a circle in terms of the circle's radius

is

Differentiating both sides with respect to

, you get
Answer:

Step-by-step explanation:
radius of the base times height is supposed to equal the volume but I'm bad at geometry
Plug in e for 3.
10(3+7)
Use the distributive property. a(b+c)= ab+ac
10*3= 30, 10*7=70
30+70=100
The expression equals 100.
