Answer: A= 460 mm2
Step-by-step explanation:
Hi, since the circumference formula is :
C = 2 π r
Where r is the radius, we can solve the formula for the radius replacing with the value given:
76 =2 π r
76 / (2 π) = r
r = 12.1 mm
Now , we have to apply the formula for the area of a circle.
A = π r^2
A = π (12.1)^2
A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)

Answer: M = 3
Step-by-step explanation: you have to use the slope intercept form y = mx+b to find the actual slope
Answer:
2013
Step-by-step explanation:
We note that 2013 has the property: since the sum of the digits of 201, 2+0+1=3, is divisible by 3, 201 is itself divisible by 3. We must now check whether any odd-numbered years before 2013 have the property. 200 is not divisible by the prime 7, so 2007 does not have this property. Likewise, the sum of the digits of 200 is 2, which is not divisible by 3, so 200 and 9=3^2 are relatively prime. Clearly 2011 does not have the desired property since every natural number is relatively prime to 1. Thus, the first odd-numbered year after 2006 that has the desired property is 2013.
