ANSWER:
The surface area of the star is 3.2700 x 
square kilometres.
EXPLANATIONS:
Diameter of the star = 1.8083 x 
Km.
Surface area of the star = 4
Where n is the radius of the star.
So that;
n = 
= 0.90415 x
n = 0.90415 x Km
Thus,
Surface area = 4 x 
= 326994889
Surface area = 3.2700 x 
Therefore, the surface area of the star is 3.2700 x square kilometres.
Answer:
Step 1: Calculate the change by subtracting old cost ($50) from the new cost ($64)
Step 2: Divide that change by the old cost ($50). You will get a decimal number
Step 3: Convert the decimal number to a percentage by multiplying by 100%
Step-by-step explanation:
Try this first
2(2y^4 + 7y^3 - 4y^2 -20)
___________________
Y^2
4y^2 - 40/y^2 + 14y - 8
2(-2y^4 - 7y^3 + 4y^2 + 20)

The unit of time that will make the statement true is "day"
<h3>What unit of time will make the statement true?</h3>
The conversion equation is given as:
Seconds + Seconds/? * day = seconds
Represent the blank with a variable (x)
So, we have:
Seconds + Seconds/x * day = seconds
Subtract "seconds" from both sides of the equation
So, we have:
Seconds/x * day = seconds
Divide both sides of the equation by "seconds"
So, we have:
1/x * day = 1
Multiply both sides by x
x= day
Hence, the unit of time that will make the statement true is "day"
