V = Volume of the spherical tank = 11000 ft³
d = diameter of the sphere = ?
Volume of water in the tank is same as the volume of sphere
The formula for Volume of spherical tank is given as
V = (π/6) d³
so
d³ = 6V/π
d = ∛(6V/π)
inserting the values given above
d = ∛(6(11000)/3.14)
d = ∛(66000/3.14)
d = ∛(21019.11)
d = 27.6 ft
Answer:
a=9 , b=14
Step-by-step explanation:
Just do the operation (x+7)(x+2)
x(x)+x(2)+7(x)+7(2)
x^2+2x+7x+14
x^2+9x+14
So a=9 and b=14
