The equation for the area of a circle is:
. Insert 9 as your radius (r) into the equation and solve:
\pi 9^2 = 254.469
36/27=1.3
7x1.3=9.1
The actual length is 9.1meters
Answe
Step-by-step explanation:
The interior angles of a triangle add up to 180. We know from the photo that there is a 90° angle and an 18° angle, and 90-18 is 72, so the other interior angle is 72°. The question is asking you to find the value of side x, so you'll need to use sin.
sin (72°) = x/16
x ≈ 15.2
Right around 75 I would believe
