Answer:
1048.32 or 432 pi
Step-by-step explanation:
12*12=144
144+(4/3 pi *6^3)
6*6*6=216
216*4/3pi=864/3
864/3=288
288*3.14(pi)=904.32
904.32+144=1048.32
(If you have the pi symbol the answer is 144+288=432pi)

Answer:
1) First term = -105/2
2) The first option is the correct answer 9/2[ 2 + 26]
Step-by-step explanation:
It is given that,
The first term of the arithmetic sequence in which.... a27=-1/2
and the common difference is 2
<u>To find the First term
</u>
First term of an AP be a and common difference d the nth term can be written as,
an = a + (n-1)d
Here n = 27
d = 2 , a27 = -1/2
a + (26 x 2) = -1/2
a = -105/2
From the figure We get an = 3n - 1
<u>To find first term a1 and ninth term s9</u>
a1 = 3 x 1 - 1 = 2
a9 = 3x 9 - 1 = 26
<u>Sum of nth term of an AP </u>
n/2[first term + Last term]
first term a1 and Last term = 26
<u>Sum of first 9 terms S9
</u>
S9 = 9/2[ 2 + 26]
First option is the correct answer
