Answer:
Step-by-step explanation:
-The volume of a cone is given by the formula:
Where:
- r is the cone's radius.
- h is the cone's height.
#We substitute for r and h in the formula to solve for V:
Hence, the each cone's volume is

Answer:
32.5
Step-by-step explanation:
% over 100 = is/ of
50% over 100 = x / 65
cross multiply
3250/ 100x = 32.5
Answer:
x = 3 + i+√5
x = 3 + i-√5
OR
x= 4 - √6
x= 4 +√6
Step-by-step explanation:
(x - 3)² +6=1
(x - 3)² + 6 = 1
-6 -6
sq root > (x - 3)² = -5
x-3 = i±√5 (i because neg. number)
x = 3 + i±√5
since its ±
two possible answers
x = 3 + i+√5
x = 3 + i-√5
Or
(x - 3)² +6=1
(x-3)+ √6= √ 1
x-3 = 1 - (±) √6
x= 4 - (±) √6
Answers
x= 4 - √6
x= 4 +√6
