We can calculate the length of AB using the Pythagorean Theorem, where:
So, replacing PA by 34 and PB by 16 and solving for AB, we get:
Then, AC = AB + BC, But AB = BC, so:
AC = 2*AB
Replacing AB by 30, we get:
AC = 2*30 = 60
Answer: AC=60
Answer:
The new volume is 1/343 of the old volume or the ratio of the new volume to the old volume is 1 to 343
Step-by-step explanation:
In this question, we are asked to state the effect of multiplying the radius of a sphere by 1/7 on the volume.
Mathematically, the volume of a sphere V can be calculated using the formula
V = 4/3 * π * r^3
Now multiplying the radius by 1/7, the new radius will be r/7
Thus the new volume here will be
V2 = 4/3 * π * (r/7)^3
V2 = 4/3 * π * (r^3)/343
Thus we can conclude that the value of the volume will be decreased by a factor of 343
Meaning the ratio of the old volume to the new volume will be 1 to 343
