A sphere with radius r and a cylinder with radius r and a height of r are shown below. How do the surface areas of these solid f
igures compare? Which statements are correct? Check all that apply. The surface area of the sphere in terms of r is 4πr2 square units. The surface area of the cylinder in terms of r is 4πr2 square units. The surface area of the cylinder in terms of r is 6πr2 square units. The surface area of the cylinder and sphere are the same. The surface area of the cylinder and sphere are not the same.
There are 12 marbles in the bag. When we first pick we have 4 blue marbles. So 4 blue marbles/12 random marbles. When we pick blue and noted, there are 3 marbles in the bag because of we didn't put it back. So when we choose again there are 11 marbles and 3 blue marbles in the bag. Choosing a blue one case is 3/11.
The last part of this case is happening as a chain. So we need to multiply our two answers.
