Using the formula A = πr^2

49 = 3.14r^2
Divide both sides by 3.14

15.6 = r^2
Get the square root

r ≈ 4
d = r * 2

So the diameter is around 8...

We know that since a diameter splits a circle in half, the arcs EF, FG, and GH must add up to 180°, half the measure of a full circle. We can then use the arc addition property to create an equation using the information we know. This equation would be (10x + 8) + 67 + 11x = 180. This can be simplified to x = 5. Therefore, the value of x is 5. Now, we can simply plug in the value of x into the expressions for EF and GH. This means that the measure of EF is 58° and the measure of GH is 55°.

Hope this helps!
