When we divide the figure in four parts, we obtain four squares with its sides of 5 centimeters of lenght, with quarter circles (two) in each one of them. The limits of the shadded area are arcs of cirncunference
To calculate the area of the shadded part, we must choose one square of 5cmx5cm and divide it in 3 sectors:
a: the area below the shaded area.
b: the area above the shaded area.
c: the shaded area.
The area of the square (As) is:
As=L²
As=(5 cm)²
As=25 cm²
The area of a circunference is: A=πR² (R:radio), but we want the area of the quarter circle, so we must use A=1/4(πR²), to calculate the area of the sectors a+c:
A(a+c)=1/4(π(5)²)
A(a+c)=25π/4
The area of the sector "b" is:
Ab=As-A(a+c)
Ab=25-25π/4
Ab=25(1-π/4)
The area of the sector a+b, is:
A(a+b)=2Ab
A(a+b)=2x25(1-π/4)
A(a+b)=50(1-π/4)
Then, the shadded area (Sector c) is:
Ac=As-A(a+b)
Ac=25-50(1-π/4)
Ac=25-(50-50π/4)
Ac=25-50+50π/4
Ac=(50π/4)-25
Ac=(25π/2)-25
Ac=25(π/2-1)
The area of each shaded part is: 25(π/2-1)
To calculate the perimeter of a shaded part, we must remember that the perimeter of a circunference is: P=2πR. If we want the perimeter of a quarter circle we must use: P= 2πR/4. But there is two quarter circles in the square of 5cmx5cm, so the perimeter of the shaded area is:
P=2(2πR/4)
P=4πR/4
P=πR
P=5π
The perimeter of each shaded part is: 5π
Answer: 456 gramos.
Step-by-step explanation:
Con una busqueda online, encontré que la imagen relacionada con este problema es la que se ve abajo.
En ella podemos ver que el envase del producto trae dos porciones.
Entonces, si una porción tiene 228 gramos, dos porciones son:
2*228 g = 456 gramos.
Y el envase tiene dos porciones, entonces el envase tiene 456 gramos.
Answer: 320 meters cubed
Step-by-step explanation: Take half of the base for the triangle(being 4 m), multiply 4 and 8 (32 m squared), and multiply 32 by 10, which results in 320 meters cubed.
The problem is asking you to solve the equation
<em>y</em> = 12<em>x</em> + <em>n</em>
for the variable <em>n</em>. To do this, subtract 12<em>x</em> from both sides:
<em>y</em> - 12<em>x</em> = (12<em>x</em> + <em>n</em>) - 12<em>x</em>
<em>y</em> - 12<em>x</em> = <em>n</em>
Answer:
Step-by-step explanation:
![\sqrt[4]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B64%7D)
has the meaning of 
That means that what you have is
which means that your final answer is
That would be the answer that I try first. In fact the question is set up in such a way that I would ignore the fact that 64^(1/3) = 4
