The surface of a sphere is given by the formula:
area=4πr²
Data:
r=30 m
area=4ππ(30 m)²=3600π m².
Answer: the area of this sphere is 3600π m².
Sum of angles in a triangle = 180°, then:
∠H + ∠F + ∠G = 180°
(x°) + (x-5)° + (3x+25)° = 180°
Remove all parenthesis and computr
x+x-5+3x+25 = 180
5x + 20 = 180
5x=160
x = 32°, then ∠G = 3x+25 = 3(32)+25 = 121°

Given:
The sequence is:
To find:
The formula for the nth term in the given sequence.
Solution:
We have,
The given sequence can be written as
The sign are alternative and the absolute value of each term can be defined by the expression 
, where n is a natural number.
So, the required formula is:
Therefore, the formula for nth term in the given sequence is .
