do 51,416×4
ans is 245,664
The <u>correct answers</u> are:
<u>Perpendicular cross-section of a pyramid is a triangle</u>.
<u>Perpendicular cross-section of an oblique cylinder is an ellipse.</u>
<u>Parallel cross-section of a sphere is a circle.</u>
<u>When a rectangle is rotated about the y-axis, a cylinder is formed.</u>
<u>When a right triangle is rotated about the y-axis, a cone is formed.</u>
Explanation:
Cutting a <u>cross-section of a pyramid</u> perpendicular to the base would form a triangle. Your "slice" would go from the apex of the pyramid straight to the base. Where the cut goes through the slanted faces of the pyramid would form the slanted sides of the triangle. Where the cut goes through the base of the pyramid would make the base of the triangle.
Cutting a <u>cross-section of an oblique (non-right) cylinder</u> would form an ellipse (oval). Since the cylinder is not right, it is slanted. This means going perpendicular to the base of the cylinder would not go straight (horizontally) through the cylinder; instead it slants, which "stretches" the cross-section, forming an ellipse.
Any <u>cross-section of a sphere</u> is a circle, since a sphere is perfectly round with no base.
When <u>rotating a rectangle</u> about the y-axis, imagine rotating a piece of paper. The shape formed by doing this would "bend" the rectangle around the axis, forming a cylindrical shape.
When <u>rotating a triangle</u> about the y-axis, we can imagine the same situation we did with the rectangle; the difference is that the triangle goes in a point, which means this new figure will be as well. This would make it a cone rather than a cylinder.

Answer:
<h2>
C. 5, 2, Tails is not a possible outcome</h2>
Step-by-step explanation:
We are presented with three items
two dices and a coin
The sample space for a dice is S=(1,2,3,4,5,6)
and the sample space for a coin is S=(head and tail)
In the options provided all are possible outcomes for the two dices and the coin except for options "C" ,and this is because "8" is not a sample space in a dice
The volume V of the workbox can be calculated by the formula:
V=a*b*c where a is the length, b is the width and c is the height.
In our case a=5'', b=31/2'' and c=4''.
When we input the numbers in the formula we get:
V=5*(31/2)*4=310 in³
So the interior volume V of the workbox is V=310 in³.
