Answer:
V = 2304π units³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = πr³ ( where r is the radius ) , then
V = π × 12³
= π × 1728
= 4π × 576
= 2304π units³
Road learning: Just take out one 0 for tens, two 0 for hundreds and three 0 for thousands. The answer is 600.
Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :
The discriminant of this equation is :
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
