If an area in the form of a circle is to be roped off by a rope 10 m long, what will be the radius of this area? round your answer to two decimal places.
a. 1.59 m
b. 2.56 m
c. 3.18 m
d. 0.31 m

A. 1.59 m

Step-by-step explanation:

To find the radius of the area we wil; simply use the formula; C = 2π R

where C is the circumference of the circle,  π is a constant that is always 3.14 approximately, except given otherwise   and R is the radius.

From the question, since the circle is formed by roping  off  a rope 10 m long, then it implies that the circumference (c) = 10

We can now proceed to substitute our values into the formula;

C  = 2π R

10 ≈ 2×3.14×R

10 ≈ 6.28R

Divide both-side of the equation by 6.28

(At the right-hand side of the equation 6.28 will cancel-out 6.28 leaving us with just R while at the left-hand side of the equation, 10 will be divided by 6.28)

1.592≈R

R≈1.59 m

Therefore, the radius of this area will be 1.59 m

is means division by fractions
