The area of a circle is pi * radius squared, thus the area of the circle is 64(pi). Since we have a sector with 90 degree angle, the area of the sector is exactly 1/4 the area of the entire circle, or 16(pi)
Just multiply 3.62 by 2.12 then times it by 3
so
3.62x2.12=7.67x3=23.0
then divide it by the side of it 23.0/5=4.6
4.6 is your answer if it doesn't fit round it to 5
