Answer:
a)18.8
b)20
Step-by-step explanation:
Basically, you have to add all the numbers from the data set (188) then divide them by 10 and that equals 18.8
The second part you have to add 32 to 188 ( which equals 210) and that by 11 which equals 20
Answer:
Part A) The diameter of the rug is
Part B) The radius of the rug is
Part C) The area of the rug is
Step-by-step explanation:
Part A) Find the diameter of the rug
we know that
The circumference of a circle (circular rug) is equal to
where
D is the diameter
we have
substitute the values and solve for D
Part B) Find the radius of the rug
we know that
The radius of a circle (circular rug) is half the diameter
we have
substitute
part C) What is the area the rug is covering?
The area of the circle (circular rug) is equal to
we have
substitute
Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]
This will NOT form a triangle. The longest side (50) is greater than the sum of the other 2 sides.
