To find the circumference you do 2x3.14 times radius and for the area you do 3.14 times the radius^2 area for a would be 78.5mm and circumference would be 31.4mm and for b the area is 113.04in and circumference is 37.68
The answer is B) 254 inches^2.
You get this by squaring the radius and multiplying by pi
Step-by-step explanation:
Given n = 4
2n = 2* 4= 8
n + 2 = 4 + 2 = 6
3(n + 4) = 3( 4 + 4) = 3 * 8 = 24
Hope it will help :)
Trick question. It isn't any of the above. Any number divided by 0 is undefined.
