total = 164.48 is that an option? hmm, yes the bottom two choices.. now the perimeter . the perimeter is made up of the 2 circles
the circumference of a circle is 2
r
2*
*r
2*
*4 =25.1327 that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26
sooo
the 3rd choice looks good :)

Mikhail's age is 25 years old
Step-by-step explanation:
