What is the exact area of a circle with a diameter of 18 feet?

The formula for the area of a circle is 

\pi  r^{2}

We know the diameter, and the radius is half of the diameter.  So the radius is 9.  Now we plug that into the formula.

\pi  9^{2} =81 \pi

So the answer is B, 81 pi square feet

Step-by-step explanation:

Given the following refrigerator characteristics :

brand name and model - - > CATEGORICAL

whether it has a top freezer, bottom freezer, or side-by-side LAYOUT - - > CATEGORICAL

the estimated energy consumption per year (kilowatts); - - - > QUANTITATIVE

whether or not it is Energy Star COMPLIANT - - > CAREGORICAL

the width, depth, and height in INCHES - - - > QUANTITATIVE

both the freezer and refrigerator net capacity, in cubic FEET - - - > QUANTITATIVE

To start with ; Categorical and quantitative variables differ most notably in the fact that, quantitative variables deals with numbers, measurements or calculated mathematical values of certain attribute in a measured species or sample. Categorical variable on the other hand mostly deals with making distinctions in properties of a sample by grouping the varibale into the different available categories based on their attributes.

1. Write the equation for a line in point slope form that had a slope of 4 and passes through (1,1)
Dahasolnce [82]

Solution:

<u>Note that:</u>

  • Slope = m = 4
  • Given point: (x₁,y₁) = (1,1) [x₁ = 1; y₁ = 1]
  • Formula: y - y₁ = m(x - x₁)

<u>Use the formula to convert the line in point slope form.</u>

  • y - y₁ = m(x - x₁)
  • y - 1 = 4(x - 1)

The equation of the line (In point slope form) is y - 1 = 4(x - 1).
