1 answer:
Answer:
a) A = kB
b) 20
c) 9
Step-by-step explanation:
A is directly proportional to B when A = 12, B = 3
a) find a formula for A in terms of B
A ∝ B
A = kB
Where k is constant of proportionality
when A = 12, B = 3
12 = 3k
k = 12/3
k = 4
b) find the value of A when B = 5
A = kB
k = 4
A = 4 × 5
A = 20
c) find the value of B when A = 36
k = 4
A = kB
B = A/k
B = 36/4
B = 9

9 : 2 = 18 : 4
As: 9 x 2 : 2 x 2 = 18 : 4
--------------------
36 : 8 = 18 : 4
As: 18 x 2 : 4 x 2 = 36 : 8
--------------------
72 : 16 = 18 : 4
As: 18 x 4 : 4 x 4 = 72 : 16

Answer:
1,788
Step-by-step explanation:
You calculate the volume of the cylinder minus the volume of the cube
![volume = (\pi*r^2*height) - (width*lenght*height)\\ volume = (\pi*10^2*6) - (4*4*6) [yards]\\volume = 1,788](https://tex.z-dn.net/?f=volume%20%3D%20%28%5Cpi%2Ar%5E2%2Aheight%29%20-%20%28width%2Alenght%2Aheight%29%5C%5C%20volume%20%3D%20%28%5Cpi%2A10%5E2%2A6%29%20-%20%284%2A4%2A6%29%20%5Byards%5D%5C%5Cvolume%20%3D%201%2C788)
