What is the distance between the points (-2,4) and (6,-4), rounded to the nearest tenth
jarptica [38.1K]

9514 1404 393

Answer:

  11.3 units

Step-by-step explanation:

The distance can be found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((6 -(-2))² +(-4-4)²) = √(8² +(-8)²) = √(64·2)

  d = 8√2 ≈ 11.3

The distance is approximately 11.3 units.

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
