Note that
- 36=1·36;
- 36=2·18;
- 36=3·12;
- 36=4·9;
- 36=6·6.
If neither (length and width) is divide by 6, then cases 1, 2, 3 and 5 are extra, because
- 36:6=6 (is divide by 6);
- 18:6=3 (is divide by 6);
- 12:6=2 (is divide by 6);
- 6:6=1 (is divide by 6).
The only possible dimensions are: width - 4 cm and length - 9 cm.
Then the perimeter is
cm.
Answer: 26 cm.
Answer:
#3) (4/3) pi r^3
(4/3) pi 4^3
(4/3) pi 64
volume = 21.333pi cm^3
#4) (4/3) pi r^3
(4/3) pi 14^3
(4/3) pi 2744
volume = 3658.666pi cm^3

Answer:
26
Step-by-step explanation:
Firstly, plot the points on graph paper which you can find on the internet. The first number in the ordered pair, (the ones in parenthesis), is the x coordinate. The other number is the y coordinate. Put these onto a graph which is attached. The perimeter is 26.
Answer:
The numbers are 91 and 81
Step-by-step explanation:
Let:
x be the first number.
y be the second number.
The sum of two numbers is 172.
x + y = 172
Their difference is 10.
x - y = 10
Try to arrange for solving x:
x - y = 10
x = 10 + y
Now substitute the x to the first equation.
x + y = 172
(10 + y) + y = 172
10 + y + y = 172
10 + 2y = 172
2y = 172 - 10
2y = 162
y = 162 ÷ 2
y = 81
Now solve for x:
x + y = 172
x + (81) = 172
x = 172 - 81
x = 91
Now let's check one more time:
The sum of two numbers is 172:
91 + 81 = 172
172 = 172 (correct)
Their difference is 10:
91 - 81 = 10
10 = 10 (correct)
