This is easy bro,
So first, all you have to do is finding the half circumstance,
the formula for circumstance is:
C=π*d
since the diameter is 8, therefore,
C=π*8
C=8π,
using 3.14 for π,
8*3.14=
25.12
Hope this helps!!!!
Answer:
c) 1,381.5.
Step-by-step explanation:
First term = 3.1 *1 - 2 = 1.1
2nd term = 3.1*2 - 2 = 4.2
3rd term = 3.1*3 - 2 = 7.3
so the common difference d = 3.1.
S30 = (30/2) [ 2* 1.1 + (30-1) * 3.1)]
= 1,381.5.
