Answer:

Step-by-step explanation:
The circumference of a circle can be found using the following formula:

where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.

The radius is 15 feet.

Multiply.

Now we know the diameter. Substitute 30 feet in for d.


We are using 3.14 for pi, so substitute it in.

Multiply.

The circumference of the circle is 94.2 feet.
Answer:
20 gallons
Step-by-step explanation:
The living room is made up of white trim and blue surface area between the walls. Since the ratio of the blue surface area between the walls to the white trim is given by 1 : 10.
Also 2 gallons of blue paints are used for the walls, let x represent the number of white paint used in gallons. Hence:
number of white paint in gallons = [1 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints
2 = 1/11 * total number of paints used
total number of paints = 22 gallons
number of white paint (x) = [10 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints
x = 10/11 * 22
x = 20 gallons
Therefore 20 gallons of white paint was used
