Answer:

28.26

Step-by-step explanation:

The circumference of a circle is equal to 2πr, where r is the radius. The radius is the distance from the center of the circle to a point on the outside of the circle.

To find the circumference you can <u>plug in the known information</u> and multiply. However, instead of using actual pi, we will use 3.14 because that is what the question says.

  • 2 * 3.14 * 4.5 = 28.26

This means that the distance around the rug is 28.26 feet.

What is the greatest common factor of 24, 36, and 72?<br><br> A) 9 <br> B) 12 <br> C) 24 <br> D) 18
den301095 [7]

Answer:B

Step-by-step explanation:

You can find the GCF by seeing if the number is divisible so for 9 24/9 isn’t a integer so no for 12 24 36 and 72 are divisible so it maybe the answer for 24 36/24 isnt a integer for 18 24/18 isn’t a integer

The area of the circle is 28 ft square.

The area of the triangle is 30 ft square.

Step-by-step explanation:

1) The area of the circle= π*r^2

where π= 3.14(default value) and "r" is the radius of the circle.

Here, Radius of the circle(r)= 3 ft

Area = 3.14*3*3

        = 28.26 ft sq.= 28 ft sq(rounded to the nearest whole number)

2) The triangle has the base= 10 feet and height= 6 feet

The Area of the triangle= 1/2(b)(h)

where "b" is the base and "h" is the height of the triangle.

Substitute b=10 and h=6 ,

Area of triangle= 1/2(10 ft)(6 ft)= 60/2= 30 feet sq.
