Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V = (3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 = (3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
Answer:
sqrt(10)
Step-by-step explanation:
sqrt(160)/16
sqrt(16)sqrt(10)/sqrt(16)
4sqrt(10)/4
sqrt(10)
Multiply 4.62 by a number that to get an integer.
Such as multiply by 5 is 23.10 so to get rid of 0.1, just multiply by 50 then it becomes 231.
so that means...
4.62 = 231 / 50
or a simple answer would be multiply by 100, then you get 462.
so....
4.62 = 462 / 100
And then simplify, it is divisible by 2 so the answer is 231/50
Answer:
B) ( x+3)² - 5
Step-by-step explanation:
Given expression
x²+6x+4
Adding '9' and subtracting '9' of given expression
⇒ x² + 2 (3) (x) +(3)² -(3)² +4
(a + b)² = a² + 2 a b + b²
⇒ ( x+3)² - 9 +4
⇒ ( x+3)² -5
Answer:
x= 1
Step-by-step explanation:
7x-4x= -1+4
3x = 3
x= 1
