How to get a radical out of the denominator?

1 answer:

5 0

You can get the radical out of the denominator by multiplying the radical on the top AND the bottom so it's like x/x=1 so you're not changing the equation. By multiplying the same radical on the top and bottom you can get the radical on the top only!

Please help me question is in the picture

Answer:

172.70 sq. ft.

Step-by-step explanation:

The surface area of a circular cone is

$SA = \pi r^{2} + \pi rl$ r = radius of base l = slant height

r = 4.4 and l = 8.1

$SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\$

SA = 3.14(19.36) + 111.9096

= 60.7904 + 111.9096

= 172.70 sq. ft.
