Answer: 1962.4 cubic mm
Step-by-step explanation:
The volume of the larger cone is 
The volume of the smaller cone is
.
So, the volume is 
You plug 8 into where n is so it's 8-5
8-5= 3 so the answer is A
Answer:
SA = 470 m²
volume = 494 m³
Step-by-step explanation:
<u>Individual areas</u>
Back = 4 x 19 = 76 m²
Top = 5 x 19 = 95 m²
sloped side = 5 x 19 = 95 m²
base = 8 x 19 = 152 m²
end = (4 x 5) + 1/2(3 x 4) = 26 m²
Total SA = 76 + 95 + 95 + 152 + (2 x 26) = 470 m²
<u>Volume</u>
volume = (4 x 5 x 19) + 1/2(3 x 4 x 19) = 494 m³
i don't really get the part after the (-4,-6) , what did u write there
