What is the volume of a cylinder with base radius 4 and height 5?
Jobisdone [24]

Answer:

251.2 units³ ; 80π units³

Step-by-step explanation:

Volume of a Cylinder is: V=\pi r^2 h

'r' is the radius.

'h' is he height.  

The cylinder has a base radius of 4 units and the height 5 units.

<h3>Using 3.14 for Pi:</h3>

V=3.14*4^2*5\\V=3.14*16*5\\V= 50.24 * 5\\\boxed {V=251.2}

The approximate volume is 251.2 units³.

<h3>In terms of pi:</h3>

V=\pi 4^2*5\\\rightarrow 4^2=16\\V=\pi 16*5\\V=\pi 80\\\boxed {V=80\pi}

The exact volume is 80π units³.

Prove that tanx+secx/<br> secx (1+ tanx/secx)=1
elena-14-01-66 [18.8K]

Answer:

See below.

Step-by-step explanation:

We need to prove that tanx + secx =   secx(1 + tanx / secx) (because their quotient = 1).

Taking the right side of the identity:

secx(1 + tanx / secx)     Distributing the sec x we get:

secx + tanx = the left side.
