Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
Answer:
Step-by-step explanation:
60% of 25 is equivalent to:
A. 0.6 * 25 = x
53 cards in total....2 black kings
P(picking a black king) = 2/53 = 0.037 = 3.7%
The missing angle is 13.6, since we got the sides we can find the hypotenuse of 8 and 11 and that is 13.6 ||
Making the answer: 13.6
Here is my math c=a2+b2=8.2+11.2≈13.60147
