Answer:
height of cone will be 4.80 cm answer
Step-by-step explanation:
volume of cone is given by
volume= 1/3 π r²h
where r = radius = 8 cm given
value of π = 3,14 , constant always remains this
so
320 = 1/3 x 3.14 x 8 x 8 x h
320 = 1.04 x 64 x h
h = 320/ 66.56
h = 4.80 cm answer

Step-by-step explanation:
WKT,
Volume of a cone = 1/3πr²h
320. = 1/3×22/7×8×8×h
320. = 1/3×1408/7×h
320×3×7. = 1408×h
6720. = 1408×h
h = 6720/1408
height. = 4.77cm
Therefore height is 4.77cm
