Volume of a sphere can be found by using the formula V= where r is the radius of sphere.
Lianne drew a sphere with a radius of 7 in that is r= 7 in .she has written and need to find what should be multiplied in numerator with pi.
As r= 7 she needs to multiply numerator
The number to be multiplied is 1372.
Answer:
The rational roots of the equation are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
Step-by-step explanation:
We have to find the rational solutions of the algebraic equation:
This equation could also be written as:
for finding the roots of the equation we have to find the possible values of x.
Clearly the equation has 8 roots as the degree of the equation is 8.
from the graph of the following function we could see that the rational roots of the function are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
The rest 4 roots of the equation are the complex roots.
