Question

A rectangle is inscribed in a circle of radius r. If the rectangle has length 3x, write the area of the rectangle as the product of two functions.

Answer 1

use Pythagoras

Answer 2

and then would i combine it with pie(r^2)?

Answer 3

asked about area of rectangle not the circle,so area = height X width.

Answer 4

oh ok so then it would end up as

(2r)^2 - (3x)^2 = a

Answer 5

then i would solve for a?

Answer 6

\[a = \sqrt{(2r)^{2} - (3x)^{2}}.\]
and then
area = a X 3x

Answer 7

ok thank you so much

Answer 8

ur welcome
