Question

Use the circle to answer the questions
The diameter is
cm
r = 5.4 cm
The circumference in terms of his
cm
Using 3.14 for
circle is
the approximate circumference of the
cm.

Answer 1

Answer:

Part 1) The diameter is $D=10.8\ cm$

Part 2) The circumference is $C=33.912\ cm$

Step-by-step explanation:

step 1

Find the diameter

we know that

The diameter is two times the radius

$D=2r$

we have

$r=5.4\ cm$

substitute

$D=2(5.4)=10.8\ cm$

step 2

Find the circumference

The circumference is equal to

$C=\pi D$

we have

$D=10.8\cm\\\pi=3.14$

substitute

$C=3.14(10.8)=33.912\ cm$

Answer 2

Answer:

The diameter is  

✔ 10.8

cm.

The circumference in terms of Pi is  

✔ 10.8

Using 3.14 for Pi, the approximate circumference of the circle is  

✔ 33.9
