Given the circumference of a circle is 26 pi, what is the area of the circle? Show work. Leave answer in term of pi.

Answers

Answer 1

Answer:

Answer:169pi

Step-by-step explanation:

Circumference(c)=26pi

Circumference(c)=2 x pi x radius(r)

26pi=2pi x r

Divide both sides by 2pi

26pi/2pi=(2pi x r)/2pi

13=r

Radius(r)=13

Area of circle=pi x r^2

area of circle=pi x 13^2

Area of circle=169pi

Write the equation for a line that is perpendicular to the line y=2x-3 and passes through the origin

Answers

Determine the slope

Since the equation is already given in slope-intercept form, we'd assume that the slope is the coefficient of x.

2 is the slope

To write the equation in perpendicular form, change the slope to opposite-reciprocal.

2 opposite-reciprocal is -1/2

So, the equation would be y= -1/2x - 3

Answer:

y= -1/2x - 3

Jeff had reached the highest level in his new computer game. The computer reported his score as 1.35x10^5 points. How should Jeff write his score in standard form?

Answers

Answer:

135,000 points

Step-by-step explanation:

An easier way to solve these type of questions is to understand that the $10^(5)$ is basically asking you to move the decimal point 5 spaces to the right, adding a zero in every free spot. So 1.35x10^5 would be

1.35x10^5 = 135000

In other words Jeff's high score written in standard form would be 135,000

you have to use pemdas or as other people call it ...

(p)lease (e)xcuse (m)y (d)ear (a)unt (sa)lly
parenthesis exponents multiply divide add subtract
you start with the exponent and you take 10 to the 5th power
that will equal 100000
so now you have 1.35x100000=135000
