If Sara owns one more than twice as many books that Franks has then she has twice as many plus one more. Say Frank has 12 books, multiply that by 2 and then add 1.

Your equation should look like this: S= 1 + 2x

dexar [7]

Answer:

=376.8 $m^{3}$

Step-by-step explanation:

V=n $r^{2}$ $\frac{h}{3}$ Where V is the volume , r is the radius and h is the perpendicular height .

r = $\frac{12}{2}$ m=6

h = 10m

n=3.14

v= 3.14 * 6*6 * $\frac{10}{3}$

=376.8 $m^{3}$
