Answer:
The volume of the cone is 3140cm³
Step-by-step explanation:
Volume of come = 1/3 × πr²h
r = diameter/2 = 20/2 = 10cm
h = 30cm
π = 22/7
Volume = 1/3 × 22/7 × 10² × 30
Volume = 1/3 × 22/7 × 100 × 30
Volume = 3142.86cm³
Volume = 3140cm³
Answer:
3
Step-by-step explanation:
3.4 4 isnt bigger than 5 so it goes to 0 which makes it 3
Answer:
The factored form of this is (x - 7)(x -4)
Step-by-step explanation:
In order to factor quadratic equaitons with a 1 as the first coefficient, we look for two numbers that multiply to the last number (28), but add up to the middle number (-11). To do this, we often list the factors of the last number.
Factors of 28
1, 28
-1, -28
2, 14
-2, -14
4, 7
-4, -7
The numbers -4 and -7 satisfy this requirement and are therefore the numbers we want. Now we stick them into parenthesis along with x terms in the front like this:
(x - 7)(x -4)
And that is the fully factored form.
Answer: If Percentage decrease % = 20%, (1 - Percentage decrease %) = 1 - 20% = 100/100 - 20/100 = 80/100 = 0.8 => Percentage decreased number = 0.8 × Initial value
Step-by-step explanation: Number 100 decreased by 20% (20 percent) of its value (percentage decrease) and calculated absolute change (actual difference)
