Since the sum of the angles is 360°, we need to divide 360 with the number of sides that a polygon has.
360/18=20; this polygon has 20 sides.

Answer:
60%
Step-by-step explanation:
% = Used Pool ÷ Total × 100
= 315 ÷ 525 × 100
=60%
Answer:
19596.74 yd ^ 2
Step-by-step explanation:
The first thing is to detect the data they give us, that value corresponds to the perimeter.
The perimeter has how it formulates:
p = 2 * pi * r
solving for r
r = p / 2 * pi
replacing
r = 496.12 / (3.14 * 2)
r = 79 and d
now the area is equal to:
a = pi * r ^ 2
replacing
a = 3.14 * 79 ^ 2
a = 19596.74 and d ^ 2
means that the area is 19596.74 yd ^ 2
The answer is D. {(40/41,58/41)} Hope this helps and feel free to give brainliest, rate and thanks to help me achieve expert ;)
Answer:
B: 13.5 in^2
Step-by-step explanation:
The average length of this trapezoid is (4 in + 5 in)/2, or 4.5 in.
The height is 3 in.
Thus, the area is A = (average length)(height) = (4.5 in)(3 in) = 13.5 in^2
