Answer:
Half of 3 is 1.5(new radius)
1.5^2 = 2.25
2.25 x 3.14 = 7.065
7.065 x 2 = 14.13(area of two circles)
2 x 3.14 x 1.5 = 9.42
9.42(circumference) x 4(height) = 37.68(area of lateral)
Add the given areas:
37.68 + 14.13 = 51.81 cm2 is your answer.

Answer:
0.352
or 6/17
Step-by-step explanation:
There are 17 marbles in all. There are 6 blue ones, so that means there's a probability of getting 6 out of 17, which is 6/17. To get the decimal I just divided 17 into 6 and rounded.
The total Surface Area of a right Cone is the sum of the area of its base and the lateral (side) surface.
The formula for the total surface area of a right cone is ![T.S.A=\pi rl+\pi r^2](https://tex.z-dn.net/?f=%20T.S.A%3D%5Cpi%20rl%2B%5Cpi%20r%5E2%20)
Where r is the radius, and l is the slant height
15/45 all you have to do is simplify each number to get your answer
