Answer:
Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi
Step-by-step explanation:
The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
Answer: 1 1/4s or 1.25s
Step-by-step explanation:
From the question, we are informed that this year Martin's income is 1/4 greater than his income from last year. We are further told that his income from last year is represented by s.
Therefore, hus income this year will be:
= s + (1/4 × s)
= s + 1/4s
= 1 1/4s or 1.25s
2(3x-1) ≥ 4x-6
Distribute the 2 on the left side: 6x-2 ≥ 4x-6
Move terms to solve for x:
2x ≥ -4
x ≥ -2
Therefore, any value from -2 to ∞ are valid solutions.
The right answer is Option C.
Step-by-step explanation:
Income = $69000
Gain = $3000
Total earned= Income + Gain
Expenses on operating activities = $33000
Expenses on non operating activities = $8000
Total expenses = 33000+8000 = $41000
Profit = Total earned - Total expenses
The net profit made by Spila was $31000.
The right answer is Option C.
