Answer:
The answer in 2 decimal places is 335.01 square inches
Step-by-step explanation:
From the problem, the figure has 3 circles inside the rectangle.
The shaded area is the area of the rectangle minus the areas of the 3 circles.
The rectangle has a dimension of 18 in by 30 in.
The circles have radii of 6 in, 9 in and 12 in.
Calculate the areas :
For rectangle :
A=l x w
A=30 x 18=540

Answer:
The required recursive formula is:
Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let represents the nth term of the sequence.
This means that:
As the common ratio is -3.
so,
Hence, the required recursive formula for the geometric sequence is:
