Answer:
(A - pi r^2)/ 2 pi r= h
Step-by-step explanation:
A = pi r^2 + 2 pi rh
First subtract pi r^2 from each side
A - pi r^2= pi r^2 + 2 pi rh - pi r^2
A - pi r^2= 2 pi rh
Now divide each side by 2pi r
(A - pi r^2)/ 2 pi r= 2 pi rh / 2pi r
(A - pi r^2)/ 2 pi r= h
Answer:
the answer is 3
Step-by-step explanation:
b will be used to determine how many books he bought since he is only buying one movie ticket the equation would be 3b + 10 = 35
S=number of 6 cent stamps
t=number of ten cen stamps
e=number of 8 cent stamps
w=number of 20 cents stamps=2
cost=500 cents
6s+10t+8e+20w=500
w=2 since two 20 cent stamps wer bought
6s+10t+8e+40=500
minsu 40 both sides
6s+10t+8e=460
divide both sides by 2 to simplify
3s+5t+4e+230
also
10 more 6 cent than 10 cent
s=10+t
8 cent stamps is 3 times 10 cent stamps
e=3t
sub
s=10+t
e=3t
3(10+t)+5t+4(3t)+230
30+3t+5t+12t=230
30+20t=230
minus 30
20t=200
divid 20
t=10
sub back
s=10+t
s=10+10
s=20
e=3t
e=3(10)
e=30
20 six cent
30 eight stamp
10 ten cent
2 twenty cent
