Answer:
Radius of the circular cloth =72.29 cm
Step-by-step explanation:
The perimeter of a circle is the length of its boundary.
The circular table cloth has a hem around its boundaries that have a length of 454 cm.
So,
Perimeter of the circular cloth= [tex]2*\pi *r[/tex]
[tex]454=2*\pi *r[/tex]
As, [tex]\pi =\frac{22}{7} =3.14[/tex]
So,
[tex]454=2*3.14*r\\\\454=6.28*r\\\\r=454/6.28\\\\r=72.29cm[/tex]
The radius of the circular cloth is 72.29 cm
Answer: radius is 72.228cm
Step-by-step explanation:
Perimeter of a circle = 2 x pi x r
Where pi is a mathematical constant of 3.1428
Perimeter = 454cm,
Radius is unknown, let radius be r
Slot the values into the formula
454cm = 2 x 3.1428 x r
454 = 6.2856r
Divide both sides by 6.2856 to get ghe value of r
r = 454/6.2856
r = 72.228cm
