they all the right answer thank me later

Answer 2

Answer:

$r=\dfrac{7}{4},C=3.5\pi\approx 10.99$

Step-by-step explanation:

It is given that,

Diameter of the circle : $d=\dfrac{7}{2}$

Radius of the circle is

$r=\dfrac{1}{2}d=\dfrac{1}{2}\cdot \dfrac{7}{2}=\dfrac{7}{4}$

The circumference of the circle is

$C=2\pi r=2\pi \cdot \dfrac{7}{4}=\dfrac{7\pi}{2}=3.5\pi$

The circumference in terms of π is 3.5π cm.  

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

$C=3.5\pi\approx 3.5(3.14)=10.99$

Therefore, the circumference is approximately 10.99 cm.
