re-write as y=mx+b

y=-3x+1

so the slope of this equation i s-3

so if a line is perpendicular to the above equation,

How can we find the volume of a cone? explain in brief .​
densk [106]

\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2h     ** where "r" is radius and "h" is height **

\sf volume \ of \ cylinder=  \pi r^2h

\boxed{ \sf \tfrac{1}{3}} as it refers to the volume of cone being 1/3 of the the volume of cylinder

Hardest, example:

given height of cone is 69 km and radius is 48 km

using the formula:

\hookrightarrow \sf volume \ of \ cone = \dfrac{1}{3} \pi (48)^2(69)

\hookrightarrow \sf volume \ of \ cone = 52992\pi

\hookrightarrow \sf volume \ of \ cone = 166479.3 \ km^3

What is the value of x in the triangle?
kvasek [131]

The value of x in the right triangle is 4 units.

<h3>How to find the side of a right triangle?</h3>

The side x of the right triangle can be found using trigonometric ratios.

Therefore,

sin 30° = opposite / hypotenuse

sin 30 = x / 8

1 / 2 = x  /8

cross multiply

8 = 2x

divide both sides by 2

8 / 2 = 2x / 2

x = 4
