netineya [11]

Answer:

Part A) The diameter of the rug is $10\ ft$

Part B) The radius of the rug is $r=5\ ft$

Part C) The area of the rug is $78.5\ ft^{2}$

Step-by-step explanation:

Part A) Find the diameter of the rug

we know that

The circumference of a circle (circular rug) is equal to

$C=\pi D$

where

D is the diameter

we have

$C=31.4\ ft$

$\pi=3.14$

substitute the values and solve for D

$31.4=(3.14)D$

$D=31.4/(3.14)=10\ ft$

Part B) Find the radius of the rug

we know that

The radius of a circle (circular rug) is half the diameter

we have

$D=10\ ft$

$r=D/2$

substitute

$r=10/2=5\ ft$

part C) What is the area the rug is covering?

The area of the circle (circular rug) is equal to

$A=\pi r^{2}$

we have

$r=5\ ft$

$\pi=3.14$

substitute

$A=(3.14)(5)^{2}$

$A=78.5\ ft^{2}$

A square is inscribed in the circle. A point in the figure is selected at random. Find the probability that the point will be in

Snezhnost [94]

Ok
Probability (the point will be on unshaded part) = area of unshaded part / area of the circle.

= pi r^2 - s^2
-------------- where r = radius of circle and s = length of the side of the square.
pi r^2

The large puppy weighs 20.97 Pounds. This is because 2/3 of a hundred is 66. You would do 4.5 Times 4.66. This equals 20.97. It can be rounded to 21. Hope this helps!
