The area enclosed by the figure is 4533.48 square meters.
<u>Step-by-step explanation:</u>
Side length of the square = 42m
The semicircle is attached to each side of the square. So the diameter of the semicircle is the length of the square.
Radius of the semicircle = 21m
Area of the square = 42 x 42 = 1764 square meters
Area of 1 semicircle = π(21 x 21) /2
= (3.14) (441) /2
= 1384.74/2
= 692.37 square meters
Area of 4 semicircle = 4 x 692.37
= 2769.48 square meters
Total area = 1764 + 2769.48
= 4533.48 square meters
The area enclosed by the figure is 4533.48 square meters.
3.2128 is a rational number
A) Angle A has to be congruent to Angle D
Volume = 1/3 pi r^2 h
= 1/3 * 10^2 *81 pi
= 2700 pi units^3
Its C
Answer:
Step-by-step explanation:
The model shows that there are 40 tiles which were divided into 4 per group. This results into 10 groups. That is:
Therefore, the expression modeled by the arrangement of the tiles is
