The equation for the volume of a pyramid is (l*w*h)/3
since the problem gave you the base area, that would be the l *w
so now you would need to multiply the base area by the height, then divide by 3
16 * 15 = 240
240/ = 80 cubic centimeters
I think its 31 but im not 100% sure :)
Answer:
2139m (total area)
Step-by-step explanation:
I am like 98% sure this is right
23* 31= 713 (1 side area)
713+713=1426 (2 sides area)
31-12=19 (middle height)
19*23= 437 (middle area)
437+1426=2139m (total area)
Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14*
(4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)
h
=(1/3)*3.14*
*9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
