Answer:
sum of exterior angles of a polygon = 360°
therefore,
x + 5 + x + 10 + 3x - 8 + 5x + 10 = 360°
10x + 17 = 360°
x + 17 = 360 ÷ 10 = 36
x = 36 - 17 = 19
x = 19
<h3>rounding off 19 to nearest hundred = 20 </h3>
value of x will be 20
Tenemos que sean x e y los lados de la huerta entonces el perímetro sería:
P = 2*x + 2*y
Sabemos que el perimetro es 140, reemplazando:
140 = 2*x + 2*y
x + y = 70
despejamos y, nos queda:
y = 70 - x
Ahora tenemos que el área sería:
A = x*y
reemplazamos y:
A = x*(70 - x)
A = 70*x - x^2
Esta sería la ecuación que modela el área de la huerta.
Derivamos e igualamos a 0:
0 = 70 - 2*x
x = 70/2
x = 35
ahora calculamos y:
y = 70 - 35
y = 35
El área máxima sería:
A = 35*35
A = 1225 m^2

Answer:
The area of base is Pi r^2.
Step-by-step explanation:
The area of the base is PiR^2 since the base is a circle and the area of the circle is pi r^2.
