Answer:

15.7 feet

Step-by-step explanation:

What we are looking for here is the perimeter/circumference of the table. The formula for the circumference of a circle is diameter x pi. The diameter is 2x the radius so I did 5 x 3.14, 3.14 being in place for pi. Hope this helps! : )

Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two dista
svlad2 [7]

Answer:

A is the midpoint

Step-by-step explanation:

Given

A(5.2) B(6,-3) and C(4.7)

Required

Which is the midpoint

Midpoint is calculated using:

(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)

Testing A as the midpoint, we have:

(5,2) = \frac{1}{2}(6+4,-3+7)

(5,2) = \frac{1}{2}(10,4)

(5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)

(5,2) = (5,2)

<em>The above equation is true. Hence, A is the midpoint of B and C</em>
