Answer:201 in squared
Step-by-step explanation:
a right circular cone has
a diameter d=8+in ...........r=4+in
a height of h=12+in
the volume
the vomue 1/3 times pie times r squared times height
the vlolume 1/3 times pie times 4 in squared times 12in
the vlolume 1/3 times pie times 16 in squared times 12 in
the vlolume 192 times pie inches squared over 3
the vlolume 200.96 in squared
whcih should equal 201 inches squared.
Answer:
element remained after 14 minutes = = 7.091 g =~ 10 g
Step-by-step explanation:
After every minute the amount remained will be
(100 - 26.9 ) % i.e. 73.1 %
which is 0.731 times as much as the amount was at the start.
if the number of minutes passed is represented by t the function f(t) represents the mass of element remaining our equation will be
f(t) = 570( 0.731) ^ t
t= 14 minutes
f(14) = 570 ( 0.731) ^ 14
= 7.091 g =~ 10 g
