Answer:
The sum is -159964.
Step-by-step explanation:
Since, the sum of a geometric sequence is,
or
Where, a is the first term of the sequence,
r is the common ratio,
n is the number of terms,
Given, sequence,
–4, 24, –144, …....., up to 7 terms,
Thus, a = - 4
And, n = 7,
Since, |-6| > 1
Therefore, the sum of the given sequence is,
14 * 8 = money given out
#of people given money * (times) amount per person.
Diameter of sphere = 18 cm
Diameter = 18 cm
r = 18÷ 2 = 9 cm
h = 12 cm
= π * 9 * 9 * 12 cm³
Solid cylinder is melted and turned into a solid sphere.
Volume of sphere = volume of cylinder
Area of rectangle is 741.12km^2
Area of square is 1474.56km^2
Formula for Area of a rectangle= length x breadth
Area = l x b = 19.3 km x 38.4 km (substitute the numbers)
Area = 741 km^2
OR
Area of square = length x length
Area = l x l = 38.4 x 38.4
Area = 1474.56 km^2
