Answer:
Step-by-step explanation:
we know that
Area of a circle is equal to
A=pi* r^{2}
where
r is the radius
in this problem we have that
A=50 m^{2}
A=pi* r^{2} \\ r= \sqrt{A/pi} \\ r= \sqrt{50/pi}
r=4 m
we know that
the diameter is two times the radius
so
D=2r \\ D=2*4 \\ D=8 m
<span>We first need to know how much fencing would be needed. We can get this from the perimiter of the playground, knowing that it is a rectangle:
then we need to convert to yards to compare to the avialble fencing:
and since 72yd<75yd, yes there is enough fencing.</span>
The correct answer isthe sum of all the internal angles of a convex pentagon is 540. Also, if the pentagon is regular, each of its internal angles measures 108 degrees. Therefore, the correct answers for this case would be:The value of x can be found as the sum: x + (x + 8) + (3x-11) + (x-8) + (2x + 7) = 540 resulting in x = 68.Then, (68 + 8) = 76; (3 * 68-11) = 193; (68-8) = 60; (2 * 68 + 7) = 143 and (x) = 68The correct answers are: B: 68, E: 193, C: 76, A: 60.

MATH
You know each side is 9 meters long, meaning it’s a square. To find perimeter, add up all the sides aka. 9+9+9+9=36. To find the area, multiply one side by the other aka. 9x9 = 81.
