Answer:
The perimeter of the given semi-circle in terms of is
cm
Step-by-step explanation:
Given that the diameter of the semi-circle is 18cm
That is d=18cm
Therefore radius
Therefore radius r=9cm
To find the perimeter of the semi-circle :
perimeter of the semi-circle
cm (where r=9 cm )
cm
The perimeter of the given semi-circle in terms of is
cm
The answer is 2 well that’s what I got
Answer:
A = 1133.54 cm^2
Step-by-step explanation:
Remember, our diameter is twice the length of our radius.
Diameter = 2 * Radius
Our diameter is 38 cm, meaning our radius is 19 cm.
A = pi * (r^2)
A = 3.14 * (19cm)^2
A = 3.14 * 361cm^2
A = 1133.54 cm^2
Answer:
B
Step-by-step explanation:
If you arrange a statistics in order from least to greatest, the middle number is the median.
If there is even number of numbers in a list, let it be n numbers, then we take the average of n/2th and n/2 + 1 th terms.
Here, all of them have 6 numbers, so 6/2 = 3 and 4th, we take average of 3rd and 4th number to find the median.
Since they are arrange in order we check each:
Jon = average of 6 and 7, (6+7)/2 = 6.5
Leroy = average of 6 and 8, (6+8)/2 = 7
Simon = average of 5 and 6, (5+6)/2 = 5.5
Leroy's median is the greatest (7).
