1. Find the perimeter of the square then the circumference of the circle then subtract the circle from the square.
Area of square=length of side squared=9.8^2=96.04.
Area of circle=(pi*radius)^2=((22/7)*(9.8/2))^2
2. Area of circle=pi*r squared
38.5=((22/7)*r)^2
Solve for r
Square root of 38.5/(22/7))=r
calculate area using above formula
Answer:
4
Step-by-step explanation:
46.4 inch
Step-by-step explanation:
Area=l×b
93.6 =5.2×b
93.6/5.2 =b
So b= 18
Again,
p=2(l+b)
p=2(18+5.2)
p= 2×23.2
p=46.4
Should be four times to get in between 9 and 10
