Answer:
616 cm²
Step-by-step explanation:
To find the area of a circle you use the formula A = π · r²
So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.
196 × (22/7) = 616
0.09 - 0.089 = 0.001
Therefore, 0.09 is bigger than 0.089 by 0.001.
Answer:
Equation of line is:
![y=-15x+22](https://tex.z-dn.net/?f=y%3D-15x%2B22)
Step-by-step explanation:
Given points:
(2,-8) and (1,7)
To write the equation in point slope form.
Solution:
In order to find the equation of line, we will find the slope of the line by slope formula.
The slope
of the line passing through points
and
is given as:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Thus, slope of given line can be given as:
![m=\frac{7-(-8)}{1-2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B7-%28-8%29%7D%7B1-2%7D)
![m=\frac{7+8}{-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B7%2B8%7D%7B-1%7D)
![m=\frac{15}{-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B15%7D%7B-1%7D)
∴ ![m=-15](https://tex.z-dn.net/?f=m%3D-15)
The point slope of the equation for line with slope
passing through point
is given as:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Using point (1,7) to find the equation of line.
![y-7=-15(x-1)](https://tex.z-dn.net/?f=y-7%3D-15%28x-1%29)
Using distribution.
![y-7=-15x+15](https://tex.z-dn.net/?f=y-7%3D-15x%2B15)
Adding 7 both sides.
![y-7+7=-15x+15+7](https://tex.z-dn.net/?f=y-7%2B7%3D-15x%2B15%2B7)
[Answer]
Answer:
Hey there!
The width is 3 inches, and in real life it would be 90 inches. (3x30)
The length is 5.5 inches, and in real life it would be 165 inches. (5.5x30)
90 inches is 7.5 feet
165 inches is 13.75
13.75 times 7.5 is 103.125, so rounded to the nearest integer, that would be 103 ft^2.
Hope this helps :)
