We know that
the area A of the circular cross section of the pipe is
A=pi*r²
D=20 cm------------- > r=D/2=20/2=10 cm
then
A=pi*10²=100*pi cm²
the answer is A=100*pi cm²
Answer:
C.
Step-by-step explanation:
360/3 = 120
perimeter = 20 +20 +24 = 64 feet
area = 12^2 + x^2 = 20^2
144 + x^2 = 400
x^2 = 256
x = sqrt(256) = 16 feet
area = 1/2 x 16 x 24 = 192 square feet
cost = 192 x $2 = $384
Answer:
5
Step-by-step explanation:
Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (7,6) and p2 (2,6)
The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula
d= √((X2-X1)2+(Y2-Y1)2)
d = √(2-7)2+(6-6)2
d = √((-5)2+(0)2)
d= √(25+0)
d = √25
The distance between the points is 5
Answer:
d.
Step-by-step explanation:
A, B, and C ask questions that will be answered with different sets of data.
<u>example a:</u>
purple- 11 students
blue- 5 students
orange- 7 students
<u>example b:</u>
math- 27
history- 30
art- 25
<u>example c:</u>
history books: 12 lbs
math books: 15 lbs
science books: 10 lbs.
If it were to ask how many windows are there in each of the classrooms then it would be statistical.
you get the gist lol.
