A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round answers to nearest tent

AlexFokin [52]

Answer:

39.275

Step-by-step explanation:

the diameter of the semicircle is 10

A semicircle is half a circle, and a quarter circle is 1/4 of a circle.

Perimeter of a semicircle is ¶d/2

= 3.142 x 10/2 = 3.142 x 5 = 15.71

For 2 semicircles that will be 15.71 x 2 = 31.42

For the quarter circle, perimeter is ¶d/4 = 3.142 x 10/4 = 3.142 x 2.5 = 7.855

Total perimeter = 31.42 + 7.855 = 39.275

Find the slope of each set of points.

Elza [17]

Answer:

1. (4, 3) and (-3, 4) has Slope = -1/7

2.(-2, 0) and (8, -4) has Slope = -2/5

Step-by-step explanation:

If two such points (a,b) and (c,d) are given, then the slope S is given as:

$S = (\frac{d-b}{c-a} )$

Now here, the given set of points are:

1. (4, 3) and (-3, 4)

Here, the slope S = $(\frac{4-3}{-3-4}) = (\frac{1}{-7}) = -(\frac{1}{7})$

⇒ S = -1/7

1. (-2, 0) and (8, -4)

Here, the slope S = $(\frac{-4-0}{8-(-2)}) = (\frac{-4}{10}) = -(\frac{2}{5})$

⇒ S = -2/5
