Rafael is building a circular table with a radius of 1.75 feet. The wood costs $32.50 per square foot. How much will it cost Rafael to make the table?​

so um your answer is in step by step

Step-by-step explanation:

I assume you just want to calculate the cost of making a circle with a diameter of 2.5 feet.

The area of a circle can be calculated using the following formula:   A = pi * r2

The radius of a circle is half of the diameter.  For this problem, the radius will be 2.5 / 2 or 1.25 feet and pi is 3.14

Then the area will be :  A= 3.14 * 1.252

A= 3.14 * 1.5625 = 4.90625 ft2

If each square foot cost $32.50, then the wood will cost $32.50 * 4.90625 = $159.45

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
