The area of a circle is 43.48cm2.
Find the length of the radius rounded to 2 DP.

3.72

(its not rounded I just calculated it and got that, hope it helps:)

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

54.667> 54.666

17.889< 17.899

these are both true
