Answer with Step-by-step explanation:
We are given that
a.



b.Radius=2.58 cm
Substitute the values in the formula and 

Hence, the area of circle =20.9 square cm
c.Area of circle=1530 square cm

Hence, the radius of circle=22.07 cm
c.Area of circle of radius 15.2 cm=
Area of circle of radius 15.1 cm=

Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .
You mind explaining it? Like the question
It's 12x. you just combine both numbers
The function will be

where y is the balance, and x is the number of month.
The raph will be a line on the xy-plain which starts at the point (0, 360), and end in the point (72, 0).
Hope it helps.
