The answer to the question is 9/45, 8/40
Answer:
D
Step-by-step explanation:
To find the percentage we must first find the area of the circle:
We can find the radius of the circle using the distance formula;
⇒ 
⇒ 
⇒ 
Now we calculate the area;
⇒ 
⇒ 
⇒ 
To get the percentage we divide the area of the circle by the square’s are and multiply by 100;
⇒ 
⇒ 
The relationship between arc, radius, and central angle in radians is:
Θ = s/r
So just plugging in the values:
Θ = (5π/3)/7 = 5π/21 ≈ 0.748 or 0.7
64 + 16 would be the answer.
Answer:
8.1 * 10^-2
Step-by-step explanation:
Scientific notation is a number with it's largest digit in the one's place and its succeeding digits following it as decimals, then multiplied by a power of ten.
Appling this knowledge to the given number, we can conclude:
0.0810
= 0.081
= 8.1 * (1/10) * (1/10)
= 8.1 * 10^-1 * 10^-1
=9.1 * 10^-2
