If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)

Answer:

Area of the circle = $113.04\;units^2$

Step-by-step explanation:

Circumference = $37.68\;units$

Circumference of the circle = $2\times \pi \times r$

As,

$\pi =\dfrac{22}{7}=3.14$

$37.68=2\times \pi \times r\\\\37.68=2\times 3.14 \times r\\\\37.68=6.28\times r\\\\r=\dfrac{37.68}{6.28} \\\\r=6\;units$

Area of a circle = $\pi \times r^2$

$=3.14\times (6\times 6)\\\\=3.14\times 36\\\\=113.04\;units^2$

A line that includes the point (7, -2) has a slope of 1. What is its equation in slope-intercept

kompoz [17]

Answer:

Y = x - 9

Step-by-step explanation:

A slope of 1 = x

So we have

Y = x

To find y intercept we do

7 - (-2) = 9

So we have a y-intercept of 9

Y = x - 9
