Answer: 3:2 and 2:3
Step-by-step explanation:
Scale factor is image/preimage.
So from A to B, the image is B and the preimage is A, so the scale factor is 6/4 = 3/2.
Similarly, from B to A, the scale factor is 4/6=2/3
Gonna do a little subbing here...
for 40 pgs of express proof reading....3 bucks per pg...c = 3
40(3) - 0.05(40(3)) = T
120 - 0.05(120) = T.....120 - 6 = T.....114 = T
so express proofreading cost 114
for 40 pgs of basic proof reading....c = 3.95
40(3.95) - 0.05(40(3.95) = T
158 - 0.05(158) = T....158 - 7.9 = T.....150.10
so basic proof reading costs 150.10
for 40 pgs of extended proof reading....c = 5
40(5) - 0.05(40(5) = T
200 - 0.05(200) = T....200 - 10 = 190
so extended proof reading is 190
no need to go further....the extended proof reading is gonna be ur answer...the best quality of editing that keeps it at 190

- Diameter (d) = 7
- Height = 8
Therefore,
- Radius (r) = d / 2
- Radius (r) = 7/2
We know that :
Substituting the values :
>> V = π × (7 / 2)^2 × 8
>> V = π × (49 / 4) × 8
>> V = π × 49 × 2
>> V = 98π
Henceforth,
