B. 2.56 m
C. 3.18 m
D. 0.31 m
Answer:
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
