A cone has a diameter of 18 in. and a height of 14 in.

Bond [772]

Cone's volume is $V = \frac{1}{3}Sh$
where S - surface area, h - height
Surface area = $\pi r^2$

r = 18/2=9
h= 14
π = 3.14
$V= \frac{1}{3} \pi r^2h= \frac{1}{3} *3.14*9^2*14= \frac{1}{3} *3.14*81*14=27*14*3.14$ [/tex]
$V = 1186.92$ $in.^3$

James has $325 in his savings account. He spends $28 a week. How many, w, weeks until he has $157 left in his account?

otez555 [7]

Answer:

6 weeks

Step-by-step explanation:

Total savings= $325

For every week, his total savings decrease by $28.

Let's form an expression for the amount of money left in his account after w weeks.

325 -28w= 157

28w= 325 -157

28w= 168

<em>Divide by 28 on both sides:</em>

w= 168 ÷28

w= 6

Thus, there are 6 weeks until he has $157.
