The area is 50.24 cm.
The formula is π·r^2.
The radius is 4 cm, and you square it. 16 cm.
Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.
Answer:
10.7cm
Step-by-step explanation:
x^2= 115
x = √115
x = 10.7
Find the length of each side 240÷12=20 20 is the other length.
12•$18=$216 for the street side and 20+20+12=52 is the total length of the other sides 52•$15=$780 is the total cost of other 3 sides 780+216=996
the total cost is $996. Hope this helped
Answer:
1104 miles
Step-by-step explanation:
Say he lives in a place in Mexico which is at a distance of <em>a </em>miles from the Mexico-America border point and the reunion is at <em>b </em>miles from the same border point, in America.
So the total distance travelled is ( a + b ) miles
( this is just sum of distance travelled in Mexico + that in America )
Given , a=747 and a+b=1851
that implies:
747 + b = 1851
So, b = 1104 miles.
Therefore he has travelled 1104 miles in America,
Answer:
15
Step-by-step explanation:
Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:
(y2 - y1)/(x2 - x1)
=> Rate of change of the line passing (1,15) and (3,45):
(45 - 15)/(3 - 1) = 30/2 = 15
