Step-by-step explanation
Question 6
The length of the wire is the circumference of the circle.
Circumference of a circle = 2πr
So, to find the area of the circle, we need the radius of the circle.
2πr = 50
r = (50/2π)
r = 7.96 cm
Area of a circle = πr²
Area of this circle = π (7.96)² = 198.9 cm²
Question 7
Scale copies of each other have all their sides in the same ratio.
Since each square has four sides that are equal in length, the two squares can easily be scaled copies of each other because whatever their lengths are, the number is constant for all four sides for each square and these two numbers can definitely be expressed as scaled copies of each other.
Hope this Helps!!!
