Find the volume of the cylinder.
Either enter an exact answer in terms of a or
use 3.14 for a
units

volume of the cylinder = 150.72units³

Step-by-step explanation:

to find the volume of this cylinder  we are given that

radius  of the cylinder= 4units

height of the cylinder = 3units

volume of the cylinder =?

solution

recall that the fomular for finding the volume of a cylinder = πr²h

volume of the cylinder = πr²h

volume of the cylinder = 3.14 × (4)² × 3

volume of the cylinder = 3.14 × 16 × 3

volume of the cylinder = 3.14 × 48

volume of the cylinder = 150.72units³

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

i think its a and d
