The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.
ryzh [129]

Answer:

Option (2). 14 m

Step-by-step explanation:

Formula to get the area of a circle 'A' = \pi r^{2}

where r = radius of the circle

Given in the question,

Area of the circle = 153.86 square meters

By putting the values in the formula,

153.86 = πr²

r = \sqrt{\frac{153.86}{\pi } }

r = \sqrt{49}

r = 7 meters

Diameter of circle = 2 × (radius of the circle)

                              = 2 × 7

                              = 14 meters

Therefore, diameter of the circle is 14 meters.

Option (2) is the answer.

Greeley [361]

Answer:

a. Non proportional

b. Proportional

c. Non proportional

Step-by-step explanation:

Here, we want to determine if each situation is proportional or not

a) Non-proportional

This is because the amount y paid in a month will be;

y = 1400x + 150

Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship

b) proportional

y = 3/4x

The value of y is dependent solely on that of x, so the relationship is proportional

c) non proportional

Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional
