This is true. A solid line means that anything behind the line is true, but dotted lines mean that points on the line are also solutions. In other words, the dotted line is the "equal to" in "greater than or equal to", so this is true.

The area of rectangle ABDE is 270 square inches. The rectangle is rotated about a line that passes through points C and F. Recta

Molodets [167]

Answer:

The answer is <u>C : a cylinder with a base radius of 9 inches</u>

Step-by-step explanation:

The area is 270² inches, and to find the area of a rectangle is width × length . So the equation would be 270 = W × L, which would convert to 270 = W × 15 and 15 times 18 equals 270. But that is not thew answer because you would need top find the radius of the cylinder which is half of the width of the rectangle which means the radius is 9. So the answer is a<u> cylinder with a base radius of 9 inches. </u>
