Question

4. Find the circumference of a circle with radius 20 ft., rounded to the nearest tenth

Answer 1

Answer:

C= 125.6

Step-by-step explanation:

The formula to find the circumference is :

$c = 2\pi \: r$

So the equation is:

$c = 2(3.14 \times 20)$

Simplify:

$c = 2 \times 62.80$

Simplify:

$c = 125.6$

And it asks to round to the nearest tenth, but it is already rounded to the nearest tenth.
