If the area of a circle is 58 square feet, find the circumference. A. 26.99 ft. B. 22.35 ft. C. 42.5 ft. D. 4.25 ft.

Answers

Answer 1

Answer: It's answer is option A. As the area of circle is given which is 58 square feet, we are to find circumference of the circle. We know that area = π r^2 Where π = 3.14 and r is radius of the circle So it will become 3.14 x r^2 = 58 r^2 = 58/3.14 r^2 = 18.4713375796 If we take square root of both sides, we get r = 4.297829403268585 feet By using this value of r we can find circumference of the circle, As, Circumference = 2 π r It will become 2 x 3.14 x 4.297829403268585 26.99036 Which is very close to the option A.

Answer 2

Answer:

The answer is A. 26.99

Brenda observes that the keyboard and the screen of an open laptop lie on two different planes. In how many lines do the planes containing the keyboard and the screen intersect?

Answers

Let's assume the laptop is opened at 90 degrees (this is done for the sake of simplicity, is actually irrelevant) then each plane would be analogous to the 'x' and 'y' planes you see in a Cartesian Plane, which only intersect at one point called the Origin. Any two lines with different slopes will intersect only one time (if they're parallel they have the same slope)

What percent of 17 is 20.4

Answers

If you would like to know what percent of 17 is 20.4, you can calculate this using the following steps:

x% of 17 is 20.4
x% * 17 = 20.4
x/100 * 17 = 20.4
x = 20.4 * 100 / 17
x = 120%

Result: 120% of 17 is 20.4.

20.4 is 120 percent (120%) of 17.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred.

So, in order to find the percent of a number we need to multiply it by the percent value and then divide it by hundred. That means if we need to find the x% of a number, we should multiply the number with x/100.

So,

17 × x/100 = 20.4

17x = 20.4 ×100

17x = 2040

Therefore,

x = 2040/17

x = 120
