Question

saroj wants to put a lace on the edge of a circular tablecloth of diameter 2m. find the length of lace required.​

Answer 1

Answer:

Step-by-step explanation:

Length of lace required would equal the circumference of table.

Length of lace required = πd =  πd=3.14x2=6.28m

Answer 2

Given:

✰ Saroj wants to put a lace on the edge of a circular table cloth.

✰ Diameter of a circular table cloth = 2 m

To find:

✠ The length of lace required to cover the circular table cloth.

Solution:

Let's understand the concept first! First we will find the radius of a circle, as we are provided with the diameter of the circle. Then we will find the circumference of the circle. Circumference of a circle refers to the whole arc of a circle i.e, the perimeter or the length of the total boundary of a circle. Therefore, the whole arc of a circle is called the circumference of the circle. The circumference or the boundary of the circle is equal to the length of the the lace required to cover the circular cloth. Like this, we can easily find out the length of the lace which is required to cover the circular table cloth.

Let's find out...✧

✭ Radius = Diameter/2 ✭

Putting the values in the formula, we have:

➛ Radius = 2/2

➛ Radius = 1 m

Now,

✭ Circumference of circle = 2πr ✭

We know that the circumference of circle is equal to the length of lace.

Therefore,

✭ Length of lace = 2πr ✭

Putting the values in the formula, we have:

➤ Length of lace = 2 × 3.14 × 1

➤ Length of lace = 6.28 m

∴ The length of lace required to cover the circular table cloth = 6.28 m
