Answer: 28
Step-by-step explanation:
The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:
a + 6d = 4
where,
a = first term
d = common difference= -4
a + 6d = 4
a + 6(-4) = 4
a - 24 = 4
a = 4 + 24
a = 28
The first term is 28.
A=3.14r^2
1. 2^2= 4
2. 3.14 x 4 =12.56 as your answer
it's 17/42... theres no whole number
