Answer:
35.0 cm (to 3 significant figures)
Step-by-step explanation:
Circumference of a circle = 2d (where d is the diameter).
Since the rectangle is inscribed in the circle (all 4 vertex touch, but not intersect, the circumference of the circle), we can see that the diameter of the circle is in fact the diagonal of the rectangle.
Therefore, to calculate the circumference we need to find the diagonal of the rectangle and plug it into the above formula.
To find the diagonal, we use Pythagoras' Theorem a² + b² = c² (where a and b are the legs, and c is the hypotenuse of a right angled triangle).
From inspection, the diagram has given us the lengths of the legs as 9cm and 15cm. So:
9² + 15² = c²
81 + 225 = c²
306 = c²
c = √306 = 3√34
Therefore, the diameter of the circle = 3√34 cm
Circumference = 2d
= 2 x 3√34
= 6√34
= 35.0 cm (to 3 significant figures)

Step-by-step explanation:
add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Answer: 3,965,481
Step-by-step explanation:
Given: In 2016, the Maricopa County population is approximately 3.817 million.
i.e. Initial population= 3.817 million =3,817,000
Of the population increases from the current population by 3.89 % over the next 5 years,
Population increased = 3.89% of 3,817,000
= 0.0389 (3817000)
= 148481.3 ≈ 148481
Population in 2021= 3,817,000 +148,481 =3,965,481
Hence, the population in 2021 = 3,965,481
Carlos will use 8 shelves with 3 novels and 2 autobiographies on each.
17 times 4, you get 68. 68 minus 35, your answer is 33
17*4=68
68-35=33
