Answer 4

the area of the whole circle is pi * r^2 where r is 4
so pi * 16 = 50.24
so yes 50.3 if you round.
(I would keep 2 decimals until the very end, then round)

next, we know a circle is 360º around. 60º is only part of the whole circle.
in other words, the "pie section" is 60/360 , which simplifies to 1/6
it is 1/6 the area of the whole circle.

Answer 5

so would the answer be D. 8.4?

Answer 6

yes

Answer 7
