The radius of a circle is 2 millimeters. What is the circle's area?

A = 4pi mm^2  or approximately 12.56 mm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the radius is 2

A = pi 2^2

A = 4 pi mm^2

We can approximate pi by 3.14

A = 4*3.14

A =12.56 mm^2

b

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
