Answer:
60.79 square yards.
Step-by-step explanation:
d = 2r; d = 8.8.
8.8 = 2r
r = 8.8 / 2
r = 4.4 yards.
Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.
4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.
Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

The answer is 2/3 but if you want it in decimal form it is 0.6
The value of cos 67.4° is 5/13.
According to trigonometric identities used in mathematics, sin of an angle is equal to cos of 90 - the given angle. Mathematically, this means that, suppose we have an angle x, then-
sin(90 - x) = cos x
Here, we are given that sin 22.6° = 5/13. As we can observe that (90 - 67.4) is equal to 22.6, and we need to find the value of cos 67.4° only. Thus we can write the given equation as follows-
sin22.6° = sin(90 - 67.4°)
= cos 67.4°
Thus, sin 22.6° = cos 67.4°
Hence, cos 67.4° = 5/13
Thus, the value of cos 67.4° comes out to be 5/13.
