Letter C is the correct answer. To get the volume of a cone, the formula we must use is V=πr²h/3. π is equivalent to 3.14, r or radius is given in the problem is 8. But if ever you...Read More

It would be 502.65 because the formula for the surface area of a cone is this:

I've calculated this two ways and came up with 360 units squared.

1) 1/2 slant height p (which is perimeter of base) + B (area of base)

1/2 (13)(40) + 100

260 + 100

376.8 units squared

Circumfrence hight + circle on top+ circle on bottom= 31.47 + 78.5 + 78.5

Circumfrence hight + circle on top+ circle on bottom= 31.47 + 78.5 + 78.5

340 units squared

Special right triangle to find height of 12. 512(.5)=30 for each right triangle, 60 for each side. 4 sides since its a square so 60+60+60+60+ base. Base =1010 so 240+100.
