Answer:
B. 12cm
Step-by-step explanation:
We can double check by plugging in the number. However, the question trys to trick you, by giving you the diametre, but in order for the formula to work (V=4
/3πr^3), we will divide the diametre by 2 (12 ÷ 2= 6),
--------------------------------------------------------------------------------------------------------------
Once we do that, we can double check, when you plug in your numbers your answer will be around 900 (904.78, to be exact, but the question asks for approximate diamtetre).

Answer:
58 square units
Step-by-step explanation:
Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.
Area of the full larger rectangle:
Area = length × width
Length = |12 - 2| = 10 units
Width = |8 - 1| = 7 units
Area = 10 × 7 = 70 units²
Area of the unshaded small rectangle:
Length = |10 - 4| = 6 units
Width = |3 - 1| = 2 units
Area = 6 × 2 = 12 units²
Area of the shaded figure = 70 - 12 = 58 square units
The area removed from the sheet of glass after being cut
The area of the sheet of glass after being cut is= x^2 -3x
Answer:
The nth term will be;
Tn = Tn-1 + 6(n-2) + 11
Step-by-step explanation:
Here, we are to find the nth term of the given equation
Firstly, we need to notice a pattern
What difference do we notice between the terms?
That would be;
16-5 = 11
33-16 = 17
56-33 = 23
next would be 29 + 56 = 85
afterwards; 85 + 35 = 120
So the pattern here is that we shall add 6 to the last common difference between the two preceding term to get the succeeding term
So what’s the nth term here?
Tn = Tn-1 + 6(n-2) + 11
So for example, the 5th term will be;
T5 = T5 + 6(5-2) + 11
T5= 56 + 18 + 11 = 85
While the 4th term will be
T4 = 33 + 6(4-2) + 11
T4 = 33 + 12 + 11 = 33 + 23 = 56
