Answer: 42.14 cm^2
square:
Area of a square=s^2
A=14^2
A=196
circle (the two semi circles are the same as one circle):
Area of a circle=(pi)(r)^2
divide 14 (diameter) by 2 to find the radius
A=(3.14)(7)^2
A=(3.14)(49)
A=153.86
subtract the area of the two semi circles from the area of the square to get the answer
196-153.86=42.14
Answer:
20 square meters
Step-by-step explanation:
area = length x width
area of grass = 4 x 4 = 16
area of grass and cement = 6 x 6 = 36
<em>Now you subtract to find the area of the cement.</em>
36 - 16 = 20
Find the common ratio by dividing.
16 / 8 = 2
8 / a = 2
2 / b = 2
The common ratio is 2.
Since we need to find the values of a and b, use the common ratio to solve for them.
8 / 2 = 4 (a)
2 / 2 = 1 (b)
Now, we know that first 5 terms.
We can solve for the 8th term using the previous terms and the common ratio.
6th term: 1 / 2 = 0.5
7th term: 0.5 / 2 = 0.25
8th term: 0.25 / 2 = 0.125
Part A: 2
Part B: a = 4, b = 1
Part C: 0.125
Best of Luck!

Take ln to both sides
ln 14^x = ln 5
then you'll get
x ln 14 = ln 5
divide both sides by ln 14
x = 0.6098533345
after rounding
x = 0.6099
