Earth has a diameter of approximately 8,000 miles. If the circumference of a circle can be found using the formula C = πd, what
1 answer:
Answer: Circumference of Earth= 25120 miles
Step-by-step explanation:
Given: The circumference of a circle can be found using the formula , where d= diameter of the circle.
Earth's diameter = 8000 miles (approx)
The circumference of circle = [substitute values in formula]
The circumference of circle = 25120 miles (approx)
Hence, the circumference of Earth= 25120 miles (approx)

The first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
Given:
where,
n = number of terms
First term, a1 = 2
Second term, a2
a2 = {(2 - 1)/ 4} - 2
= 1/4 - 2
= (1-8) / 4
= - 7/4
Third term, a3
= {(3-1) / 4} - 2
= 2/4 - 2
= 1/2 - 2
= (1-4) / 2
= -3/2
Therefore, the first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
