Answer:
Step-by-step explanation:
A=πr2
Circumference = 2πr
20π = 2πr
r=10
π=3.14
A=3.14 * 10^2
=314 cm^2
Answer:
three angles of a polygon are each 105.5,the sum of the angles in the polygon is 2520. find each of the other angles if they are equal to each other. For a polygon with n sides and n angles, the sum of the measures of all the interior angles equals (n-2)180 degrees. 16-3=13
Answer:
x = 6
Step-by-step explanation:
12x+252=324
Subtract 252 from each side
12x+252-252=324-252
12x =72
Divide each side by 12
12x/12 = 72/12
x =6
Answer:
42.9m
Step-by-step explanation:
The topic is on similar triangle
you are comparing triangle MNP with triangle MAB
side AB is similar to NP
side MA is similar to MN
side MB is similar to MP
now MA = MN - AN
= 67.2 - 32
= 35.2m
MA/MN = MB/MP
35.2/67.2 = x/81.9
cross multiply and solve
x = 42.9m
Answer:
<h2>10</h2>
Step-by-step explanation:
Let us give a proper illustration in the number line
let H be Abby's house
and S be the school
let W be her mother's work.
kindly find attached a rough sketch of the number line for your reference
Question:<em> What value represents the difference in position between Abby's house and her mother's store?</em>
basically, the distance between two points on a number line is the difference between the points.
So the value that represents the position between Abby's house and her mother's store is the distance between the two points.
= 4-(-6)
=4+6
=10
