Question

PLZZZ HELP NOOOOWWW!!!

Answer 1

Hello!

You can use the Pythagorean Theorem


`a^(2) + b^(2) = c^(2)`

C is the hypotenuse which is the line across the diameter
a and b are the other sides

You have to find the bottom side of the triangle

9 - 6 = 3

Put in the values you know


`9^(2) + 3^(2) = c^(2)`

Square the numbers


`81 + 9 = c^(2)`

Add


`90 = c^(2)`

take the square root of both sides


`√(90) = c`

The answer is
`C) √(90)`

Hope this helps!
