Answer:

area of a circle formula:

radius squared x pi(3.14 or 22/7 most likely whatever they tell you to use in pi)

Circumference formula:

2 x pi(3.14 or 22/7 most likely whatever they tell you to use in pi) x r(radius, if they dont give you the radius but just your diameter for either circumference of area just do half of the diameter shown)

Step-by-step explanation:

First problem:

In this case,

7 is your radius!

7 x 2 x 3.14 (circumference) = 43.96

now area: 7^2 = 49

49 x 3.14 = 153.86

Now time for the other problem:

half of 30 is 15!

15 x 3.14 x 2 (circumference) = 94.2

Area of the circle:

15^2 = 225

225 x 3.14 = 706.5

Answer:

Lines are parallel if the sum of external angles of same side is 180°.

Step-by-step explanation:

Let one of the external angle is α°.

and other external angle is β° which is equal to α°/11. (∵ Given on is 11 times smaller than the other.)

Also β° = 1/6 of the right angle = (1/6)×90° = 15°.

β° = α°/11 , ⇒ α° = 11×β° = 11×15° = 165°.

α°+β° = 165° + 15° = 180°.

Here, sum of the two external angles = 180° ⇔ the given lines are parallel.

Answer:

The range of given data set is 90.

Step-by-step explanation:

We are given the following data:

20.9, 33.1, 21.8, 58.5, 23.5, 110.9, 30.4, 24.9, 74.1, 60.3, 40.4, 45.4

When this data is arranged in ascending order, we get:

20.9 , 21.8 , 23.5 , 24.9 , 30.4 , 33.1 , 40.4 , 45.4 , 58.5 , 60.3 , 74.1 , 110.9

Range is a measure of dispersion and can be easily calculated.

Formula:

Range = \text{Maximum values - minimum value}

Range = 110.9 - 20.9 = 90

Thus, the range of given data set is 90.
