Answer:
30.14
Step-by-step explanation:
- The formula for cirumference is 2(pi)r
- If the diameter equals 9.6 then the radius is 4.8
- 4.8 times 2 equals 9.6
- 9.6 times 3.14(pi) equals 30.144 which could be rounded to 30.14
You have the answer correct
Answer:
a₈ = - 10935
Step-by-step explanation:
the nth term of a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
here a₁ = 5 and r =
=
= - 3 , then
a₈ = 5 ×
= 5 × - 2187 = - 10935
Step-by-step explanation:
45+90+x=180
135+x=180
x=180-135
x=45
