Answer:
First lets find the area of the bottom circle:
7.2 is your radius so:
7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.
lets continue:
51.84 x 3.14(pi) = 162.7776
Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.
2 x 3.14 x 7.2 = 45.216
Now lets multiply it by the height:
45.216 x 17 = 768.672
Now lets add both areas:
768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.
In Quadrant III, tangent is positive; both sine and cosine are negative. A helpful acronym for each quadrant is All Students Take Calculus (All positive in I, Sine in II, Tangent in III, Cosine in IV).
Answer:
1/2
Step-by-step explanation:
substitute -2 for x.
any number to negative power must be flipped. 2^-2 = 1/(2^2) = 1/4
(2)(2^-2) = (2)(1/4) = 2/4 = 1/2
Answer:
Step-by-step explanation:
Firstly you must understand you want to get the value of y.
So put in values into equation which make x.
To understand here lets look at y = 0
if y is to be 0 then x is 3.
If we substitute this value into equation (B) we get the result.
Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.
So , we can see B is the answer
