Answer:
252 cm²
Step-by-step Explanation:
=>Given:
r = 4.9 cm, and h = 3.3 cm of a solid cylinder, π = 3.14
=> Required:
Total Surface Area (T.S.A) = 2πrh + 2πr²
T.S.A = 2*3.14*4.9*3.3 + 2*3.14*4.9²
= 101.5476 + 150.7828
= 252.3304
= 252 cm² (approximated)
I'm pretty sure the answer is 12.
The true statements are:
2 - we can tell this by looking at the far right of the graph, as the slope is going downwards, therefore the leading coefficient must be negative
3 - this is a cubic, meaning its degree is 3
6 - by looking at the graph, we can see that there are 3 points where it cuts the x axis, hence 3 real zeros
7 - even multiplicity is where the curve "bounces off" the x axis and does not cross it. This curve have no zeros with even multiplicity

To answer this question you must find the percentage of the children that read before bed and compare it to the adults bag read before bed’s percentage.
To do this, start by dividing the number of children that read before bed by the total number of children surveyed.
This leaves you with:
6/13= 0.4615
To find the actual percentage, multiply this result by 100.
0.4615 x 100 = 46.15
This percentage rounded is 46%
So, now you can compare the percentages. The percentage of children that read before bed is 46% and the percentage of adults that read before bed is 54%. So, the group with the greatest percentage was the adults.
I hope this helps!
