Ok, so to find the volume of a sphere, the volume is 4/3 (3.14 which is pie) times the radius cubed so r^3
so the radius of this sphere is 2 because 4-2=2
Step-by-step explanation:
so now we do 4/3 times 3.14 times 2^3 power=
now first we multiply 4/3 times 2 to the 3rd power bc we dont need to multiply pie (3.14) your answer would be 10.66667 so its 10.66667 pie (3.14) so round 10.66667 it would just be 10.7 because the 7 round up the 6 to a 7. Hope this helps!

Select the correct answer from the drop-down menu. Find the polynomial. {5} is the solution set of.
Answers
Polynomials are expressions. The polynomial whose solution set is {5} is x²-10x+25.
What are polynomial?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
As it is given that the {5} is the solution set of the function, therefore, we can write,
[tex]x = 5\\(x-5 )= 0[/tex]
Thus, (x-5) is one of the factors of the polynomial.
Let's assume that the 5 is the only root of the polynomial, therefore, if we multiply the factor by itself we will get the quadratic equation whose solution is only 5.
[tex](x-5)^2\\\\\text{Using the algebric identity we will get}\\\\x^2-10x+25[/tex]
Hence, the polynomial whose solution set is {5} is x²-10x+25.

The area of a semicircle is 39.25 square kilometers. What is the semicircle's radius?
Use 3.14 for pi
__ kilometers
Answers
Answer:
R=5
Step-by-step explanation:
The area of a semi circle is 1/2(pi×R^2).
Since the area is given you would just work backwards.
Using 3.14 as "pi", you would have
39.25 = 1/2(3.14×R^2)
39.25*2 = 3.14*R^2
78.5 = 3.14* R^2
78.5/3.14 = R^2
25 = R^2
Then you would take the sqrt of R and 25
And the answer would come to 5 = R
R= radius
[tex] \small \tt{Area \: of \: a \: semicircle = \frac{1}{2} \times \pi {r}^{2} }[/tex]
[tex] \small\tt{39.25 = \frac{1}{2} \times 3.14 \times {r}^{2} } [/tex]
[tex] \small\tt{39.25 \times 2 = 3.14 \times {r}^{2} } [/tex]
[tex] \small\tt{78.5 \: = 3.14 \times {r}^{2} } [/tex]
[tex] \small\tt{ \frac{78.5}{3.14} = {r}^{2} } [/tex]
[tex] \small\tt{ {r }^{2} = 25} [/tex]
