Answer:
500
Step-by-step explanation:
80 * 10 ÷ 8 = 100 * 5 = 500
Answer:
12 pi
Step-by-step explanation:
First find the area of full circle
A = pi r^2 where r is the radius
A = pi (4)^2
A = 16 pi
This is 3/4 of a circle so multiply the area by the fraction of a circle
3/4*16pi = 12 pi
The rational roots of the polynomial given in the question are -4/5 and 3/4.
Given-
Given polynomial function is,

The given polynomial function has the four-degree equation in which the greatest power of the variable is four. Suppose one root of <em>x </em>is 1 to solve it further. So one factor is,

Rewrite the given equation,





On the factor above equation, we get.
