How do i find the circumference of a circle when the given radius is 3 1\2 cm, answers in terms of π ​

Circumference of circle is 97.42cm.

Step-by-step explanation:

Here we have given that A circle with having radius 31 / 2 cm. And We need to find circumference of circle.

Formula using

Circumference of circle = π × 2 × radius

substitute the value

Circumference of circle = π × 2 × 31 / 2 cm

cancle the 2

Circumference of circle = π × 31 cm

Using π = 22 / 7

Hence, Circumference of circle is 97.42cm.

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
