Question

The diameter of the circle (in feet) if the circumference of the circle is 3140 feet is
[Use π = 3.14]

• A. 100 feet
• B. 1000 feet
• C. 50 feet
• D. 10000 feet

Answer 1

The correct option is B 1000 feet

Given

Circumference = 3140 feet

$⟹\pi \times D=3140$

$⟹3.14\times D=3140\because \pi =3.14$

$⟹D=\frac{3140}{3.14}=\frac{314000}{314}$

$⟹D=1000$

So, the diameter of the circle is 1000 feet.
