Answer:

28260 cubic cm

Step-by-step explanation:

Given,

Diameter of the cylinder = 30cm

So, radius of the cylinder = 30cm ÷2 = 15 cm

Height of the cylinder = 40 cm

There, volume of the cylinder,

$= \pi {r}^{2} h$

$= 3.14 \times 15cm \times 15cm \times 40cm$

$= {28260cm}^{3}$

What is the length of AC?

Otrada [13]

Answer:

Length of AC = <u>12units</u>.

Step-by-step explanation:

$\sf\large{\star Given:-}$

Hypotenuse of the triangle = $\sf\pink{10\:units.}$
Height of the triangle = $\sf\pink{8 \: units.}$

$\sf\large{\star To\: Find:-}$

$\rightarrow$ Base of the triangle.

$\sf\large{\star Solution:-}$

$\rightarrow$ As we know that,

Pythagoras Theorem:

$\sf\blue{Hypotenuse^2\:=\: Height^2+Base^2}$

So, In triangle ABD by putting the value of hypotenuse and height in this formula we get,

$\rightarrow$ $\sf{10^2\:=\: 8^2 + Base^2}$

$\rightarrow$ $\sf{100\:=\: 64 + Base^2}$

$\rightarrow$ $\sf{100-64\:=\: Base^2}$

$\rightarrow$ $\sf{36\:=\: Base^2}$

$\rightarrow$ $\sf{\sqrt{36}\:=\: Base}$

$\rightarrow$ $\sf{6\:=\: Base}$

Since, it is given that BD is the perpendicular bisector of AC so length of AC will be doubled.

Therefore, length of AC of the given triangle = $\sf\purple{12units.}$
