Ответ:
Side Length (s) = ?
We know that,
P = 4*s
216 = 4*s
s = 54
Hence, the side is 54 cm.
Ответ:
Therefore, we can find out how long each side is by dividing 216 by 4, because a square has four sides.
216÷4=54, so each side of the painting is 54 cm.
Ответ:
C = 22.56
Step-by-step explanation:
The equation for the circumference of a circle is
.
The radius is half the diameter so![r=\frac{7.18}{2}=3.59](/tpl/images/2413/3254/e7252.png)
Plug the radius into the equation.
