Answer:
Approximately 50 square feet (50.24 to be exact)
Step-by-step explanation:
If you're using 3.14 for π, and the area of a circle is A=πr2,
(3.14)(4)^2 =?
(3.14)(16) = 50.24
Therefore the answer would be about 50 square feet.

Step-by-step explanation:
hello :
f(x) = 2x +1 and g(x) = x².
(gºf)(a)= g(f(a)) = g(2a+1) = (2a+1)² = 4a²+4a+1
Try to find out distinct shapes in the polygon and use their area formulas, then add up all of the shape's areas.
Answer:
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
Step-by-step explanation:
we know that
The isosceles trapezoid has
:
Two parallel sides not equal in length called its bases (KL and NM)
Two non-parallel sides equal in length (LM and NK)
so
![NK=\sqrt{5}\ units](https://tex.z-dn.net/?f=NK%3D%5Csqrt%7B5%7D%5C%20units)
The perimeter is equal to
![P=KL+LM+NM+NK](https://tex.z-dn.net/?f=P%3DKL%2BLM%2BNM%2BNK)
substitute the values
![P=2\sqrt{2}+\sqrt{5}+\sqrt{2}+\sqrt{5}](https://tex.z-dn.net/?f=P%3D2%5Csqrt%7B2%7D%2B%5Csqrt%7B5%7D%2B%5Csqrt%7B2%7D%2B%5Csqrt%7B5%7D)
![P=(3\sqrt{2}+2\sqrt{5})\ units](https://tex.z-dn.net/?f=P%3D%283%5Csqrt%7B2%7D%2B2%5Csqrt%7B5%7D%29%5C%20units)
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
