Question

The diameter is 1 cm. What is the circumference?

Answer 1

Answer: π
`0.5^(2)`

Step-by-step explanation: Because the diameter of the circle is 1cm

which means the radius of the circle is 0.5cm. After that, we'll find the

area of the circle the formula to find the area is
`\pi r^(2)`

r (radius) = 0.5cm

So the answer will be
`\pi 0.5^(2)`

Answer 2

3.14

C= 2 (pi) .5 cm

2*3.14*.5
