Answer:
The area of the shaded region is 5.86\ cm^{2}
Step-by-step explanation:
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
A=b^{2} -\pi r^{2}
we have
b=3\ cm
r=1\ cm
assume
\pi =3.14
substitute the values
A=3^{2} -(3.14)(1)^{2}
A=5.86\ cm^{2}
Answer:
30%

Answer:
20/3
Step-by-step explanation:
2/3 : 1/4 = x : 2 1/2 -->
2/3 : 1/4 = x : 5/2 -->
(2/3)(5/2)(4) = (x) -->
20/3 = x
Answer:
2.6Kg
Step-by-step explanation:
Let the weight of apples be x and that of pears be y .
The farmer sold 7.1 kg of apples and pears .
4.5 of the 7.1kg is apples
That’s
x + y = 7.1kg
4.5kg + y = 7.1kg
Subtract 4.5kg from both sides
4.5kg - 4.5kg + y = 7.1kg - 4.5kg
y = 2.6 kg
The farmer sold 2.6kg of pears at the market
