The diagram shows a round fountain surrounded by a circular path. The radius of the fountain is 47 yards, and the distance from the center of the fountain to the outer edge of the path is 56 yards.
The estimated area of the fountain is
v. square yards, and the estimated area of the path is square yards.
Hint: The formula for the area of a circle is A = pi r squared 2

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

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.

it is 10.6 according to my calculations
