A circular table cloth has a hem all the way around its perimiter. The length of this hem is 454cm. What is the radius of the table cloth?

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=

As,

So,

The radius of the circular cloth is 72.29 cm

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

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

make sure you have version 2.50

try looking in the very back of the book : )
