Apicture shows the net of the lateral surface of the cone. which statement about this cone is not true?
a. the height of the cone is less than 9 ft.
b. the lateral area of the cone is π • 7.5 • 9.
c. the slant height of the cone is 9 ft.
d. the area of the net is π • 92.

the answer is d

step-by-step explanation:

d is false. the net could be thought of as a circle. the area of a circle is pi*radius^2.

the ares of the "circle pictures above would be about 254ft. then you would see that about 16.7 percent of that circle is gone. you would take 254 and subtract 16% of it getting about 212

pi*92 is not about 212 so d is false
