Question 83 true or false and why ? plz ryt answer thanks

Answer 1

The answer is false.

The formula for the SA of a cone is
`\pi r^(2)+\pi rl` where r is the radius of the base and l is the slant height.
Since we have both the slant's height and the radius of the base we can answer this just by plugging numbers in;

`SA=\pi r^(2)+\pi rl\\ SA=\pi (2^(2))+\pi (2)(6)\\ SA=4\pi+12\pi\\ SA=16\pi\\`

`16\pi`≈50.2654...

So your answer is false.
