radius = (4*10^2 + 24^2)/8*10 =
(400 + 576)/80=
976/80 = 12.2
diameter = 12.2 x 2 = 24.4
Answer:
a(8) = -0.0027
Step-by-step explanation:
The most general formula for a geometric sequence is a(n) = a(1)*r^(n-1), where a(1) is the first term and r is the common ratio.
Here, the formula becomes a(n) = 6*(-1/3)^(n-1).
Substitute 8 for n to find the eighth term:
a(8) = 6*(-1/3)^(8-1), or a(8) = 6(-1/3)^7, or a(8) = -0.0027
0.94>0.49 because 0.94 is the larger number.

4)≈7.7
Answer:
2.25π square inches [or 7.07 sq. in. rounded to 2 decimal places]
Step-by-step explanation:
The largest circle inscribed in a square would have DIAMETER EQUAL TO THE SIDE LENGTH OF THE SQUARE.
Since diameter is double of radius, we can find the radius to be:
diameter = 3 [side length of square]
radius = 3/2 = 1.5 inches
The area of a circle is πr^2
THus, the largest circle area = πr^2 = π(1.5)^2 = π(2.25) = 2.25π square inches
