<span>The value of (a-1)+a^2-b^2/1-ab+2(a-b)/2b when a=2 and b=-1 will be evaluated as follows:
substituting the values in the expression we obtain:
(2-1)+2^2-(-1)^2/1-(2*(-1))+2(2-(-1))/(2(-1))
simplifying the above we get:
1+4-1/1-(-2)+2(2+1)/(-2)
=1+4-1+2(3)/(-2)
=1+4-1-3
=5-4
=1
Answer: 1</span>
15.889 or 15.8888999 because when you solve the 8 and 9 is a rbeing repeated,
Cone volume=(1/3)hpir^2
d/2=r
d=12
d/2=12/2=6=r
V=120pi
120pi=(1/3)hpi6^2
120pi=(1/3)hpi36
120pi=12hpi
divide both sides by pi
120=12h
divide 12
10=h cm
if height and diameter is doubled aka height and radius are doubled
V=(1/3)(2h)pi(2r^2)
we want to see how it compares to V=(1/3)hpir^2
V=(1/3)(2h)pi(2r^2)
V=2(1/3)(h)pi4r^2
V=8((1/3)hpir^2)
the volume is increased by 8 times
