A circle has a diameter of 6, an area of b square units, and a circumference of c units. What is the value of b + c ?
marin [14]

Answer:

Step-by-step explanation:

Diameter = 6 units

Radius = Diameter/2 = 6/2 = 3 units

Taking π=3.14

Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c

c = 18.84

Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b

b = 28.26

So,

b + c = 28.26 + 18.84 = 47.1

Can someone help with this question on math please
Mariana [72]
Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.

Jennifer wants to make a large container of lemonade. When she makes a full glass of lemonade she uses 5 drops of flavor and 12
Julli [10]

The information we have is:

5 drops of flavor are needed for 12 ounces of water.

To solve the problem, first we need to find the amount of drops needed per ounce of water, and then multiply that by the number of ounces that we need which is 1280.

The number of drops per ounce:

To find this, divide 5 drops by 12 ounces:

\frac{5}{12}

5/12 drops are needed per ounce.

The number of drops in 1280 ounces:

Now we multiply 5/12 by 1280:

\frac{5}{12}\times1280

And the result is:

\frac{5}{12}\times1280=0.41666\times1280=533.333

The number of drops needed is: 533.333

Answer: 533.333 Drops
