Answer:
Step-by-step explanation:
The length of the required lace will be 7.85 m.
Siya has a circular table cover. Its diameter (D) is 2.5 m. We have to find out the length of the lace required to put on the edge of a circular table cover.
Circumference is the length of the circle. Hence, the length of the lace will be the circumference of the circular table cover.
We will apply the formula of the circumference of the circle = 2πR to calculate the circle's circumference. Here, R is the circle's radius and π is a constant whose value is approximately equal to 3.1415....
The radius of a circle is the half of the diameter. So, the circle's radius will be = D/2 = 2.5/2= 1.25m
Now, with the use of the circumference formula, i.e. C=2πR we will calculate the circle's circumference value.
C = 2 × 3.14 × 1.25 = 7.85
Therefore, the length of the required lace will be 7.85 m.
