Answer:
surface area=602.88 in^2+
Step-by-step explanation:
top & bottom:
6^2 x Pi x2=36 x 3.14x2=226.08 in^2
vertical side:
circumference X height
2(6)(Pi)x10=2(6)(3.14)(10)=376.8 in^2
376.8+226.08=602.88 in^2
surface area=602.88 in^2
Part A: Find the area of the circle of spilled milk as a function of time, or A[r(t)]
πr^2 = π(4t)^2 =π4^2*t^2= 16πt^2
Part B: A= 16π(4)^2 = 256π= 803.84

Answer:
B
Step-by-step explanation:
(Sorry about the crude drawing)
The drawing shows what the triangle with a terminal side in Quadrant IV looks like.
Secant is the ratio of the hypotenuse to the adjacent side of the angle. In the given ratio, we can set 5 as the hypotenuse and 2 as the adjacent side (you can see them labeled in the picture).
Now, we want to find sin, which is (opposite)/(hypotenuse). However, we don't know the opposite. We can find it by using the Pythagorean Theorem:
So, the opposite side is . But, we see that since it's in the fourth quadrant, it must be negative, so we have opposite = . Now, we can find the ratio because hypotenuse = 5:
sin(θ) = .
Thus, the answer is B.

The nearest hundred will be in the hundredth place
For example, 2000
2 is in the thousands, followed by hundreds, ten, ones
to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.
So in this case 678 will equal 700
Example: if it were 644, then it would be 600
