Svetach [21]

Answer:

Option B. $11.78\ in^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3} \pi r^{2}h$

we have

$r=1.5\ in$

$h=5\ in$

substitute

$V=\frac{1}{3} \pi (1.5)^{2}(5)$

$V=3.75\pi\ in^{3}$

assume

$\pi =3.14$

$V=3.75(3.14)=11.78\ in^{3}$

A small theater with 200 seats sells two kinds of tickets for a performance. Premium tickets sell for $20 each and Standard tick

KATRIN_1 [288]

P + s = 200......p = 200 - s
20p + 15s = 3400

20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold

p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
