Answer:
i dont get this why is it crossed out
Step-by-step explanation:
A is 8 because it says in the problem
B is 15 because 24 is 3 times 8
C is 50 because 25 is 5 times 5
Right, isosceles. Right because of the square marking and isosceles because 2 sides are equal
SOLUTION:
Case: Volume of Sphere
Method:
a) The volume of a sphere whose diameter, d= 28in
The radius,
r= 28/2
r= 14 in
The Volume, therefore:

b) When half of the volume is used,

c) The radius of the halved volume

Final answer: (To 2 d.p)
a) 11494.04 cubic inches
b) 5747.02 cubic inches
c) 11.11 inches
For that case, we factor the numerator and denominator:
Numerator:

We rewrite the term of the medium as a sum of two terms whose product is:

And the sum is:
+7
Those numbers are 6 and 1.

We factor the maximum common denominator of each group:

So:

Denominator:

So, we have:

Simplifying we have left:

Answer:
Option A
