HELP FAST PLEASE!!!!!
lidiya [134]

Alright, lets get started.

The answer Sandra got is correct that is zero but there are some mistakes she made while writing steps.

2 cot(\frac{-9\pi}{2})  =  2 cot(\frac{9\pi}{2}) Incorrect step

Because as per even/odd identity,

Cot (-Θ) = - cot (Θ)

Hence

2 cot (\frac{-9\pi}{2}) = - 2 cot (\frac{9\pi}{2})

Now,

It could be written as

-2 cot (\frac{9\pi}{2}) =   -2 cot (\frac{\pi}{2})


-2 * 0

0

Hence the answer is 0. : Answer

Hope it will help :)

Find the volume of the cone.
8_murik_8 [283]

Answer:

V=471\ \text{units}^3

Step-by-step explanation:

Given that,

Radius of the cone, r = 5 units

Height of the cone, h = 6 units

We need to find the volume of the cone. The formula for the volume of the cone is given by :

V=\pi r^2 h

Substitute all the values,

V=3.14\times 5^2\times 6\\\\V=471\ \text{units}^3

So, the volume of the cone is 471\ \text{units}^3.
