Answer:

-10xsquared-x+38

Step-by-step explanation:

so,

general eqn of quadratic equation is,

axsquared+bx+c=y

where,

x and y are exchanged by coordinates given in qn

1,64a-8b+c=0

2,4a-2b+c=0

or c=2b-4a

60a-6b=0

3,36a-6b+c=8

Anybody pls solve this question and explanation btw.

Answer:

$Vol=883.6875\,\, cm^3\\$

Step-by-step explanation:

Recall that the volume of a whole sphere is given by the formula:

$Vol_{sphere}=\frac{4}{3} \pi\,R^3$

then, the volume of a semi-sphere would be half of the formula above:

$Vol=\frac{2}{3}\, \pi\,R^3$

Now, the radius R is given by half of the semi-sphere diameter: 15/2 = 7.5 cm.

which makes our calculation:

$Vol=\frac{2}{3}\, \pi\,R^3=\frac{2}{3}\, \pi\,(7.5\,cm)^3=883.6875\,\, cm^3\\$
