3m because in a square all sides are the same and there are 4 sides, so 12 ÷ 4 = 3
Answer:
Perimeter square = 8 sqrt(pi)
Step-by-step explanation:
The perimeter of a square is 4*s
The area of a circle is Area = pi * r^2
The circumference of a circle is C = 2*pi * r
C = 4 pi
4pi = 2*pi * r
r = 2
So the area of the circle is pi * r^2 = pi * 2^2 = 4pi
The square has the same area
Area = 4*pi
Square = 4*pi
s^2 = 4*pi
s = sqrt(4*pi)
s = 2*sqrt(pi)
The perimeter = 4 * 2 * sqrt(pi)
The perimeter = 8 * sqrt(pi)
There are 10 "tenths" in one whole number.
15 --> 15 whole numbers --> 15 * 10 = 150 --> 150 tenths
0.03 --> 3 hundredths --> 10 hundredths = 1 tenth --> 3/10 tenth
150 3/10 tenths in 15.03
