Answer:

6

Step-by-step explanation:

since it's a right triangle you can use the Pythagorean Theorem

2.7² + b² = 6.5²

7.29 + b² = 42.25

b² = 34.96

b = \sqrt{34.96} which equals 6 when rounded to the nearest tenth

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.
