Answer:
is your answer
Step-by-step explanation:
=
to get to 96 you must multiply by 8
and since you did that for the bottom then you need to do the same for the top,
is your answer
B 216 because if you multiply pi with the answer you get 678.58
C = 11.6239mm
Circumference Formula is C = 2πr
R = 1/2 D
R = radius
D = diameter
π = 3.14
C = circumference
1/2 3.7 = 1.85
2 x 3.14 x 1.85 = 11.6239
Sum of interior angles formula = (n-2) x 180
where n = number of sides
so,
( 19-2 ) x 180
= 17 x 180
= 3060
ans : A
hope it helps :)
