Please helpFind the unknown radius of the circle. A measures 628 sq cm find r ​

Mathematics
1 answer:
stira [4]3 years ago

Answer:

14.14 cm

Step-by-step explanation:

The formula for the area of a circle is : \pi *radius^2

In order to find the radius you would first have to divide the area of 628 by pi, this gives you 200. This is because by dividing the area by pi it will leave us with the radius squared.

The next step is to find the square root of 200, this gives us 14.14. This is because by finding the square root it will leave us with the radius. The square root is another number that when multiplied by itself equals the number.

1) Divide 628 by pi.

628/\pi =200

2) Find the square root of 200.

\sqrt{200}=14.14

Pi as in 3.14

X = 9 . to find this out, you need to plug in the given info into a^2 + b^2 = c^2 .. so we have a^2 + 6^2 = 117. Which is a^2 + 36 = 117. so we need to get a by itself. to do so, subtract 36 from both sides to get a^2 = 81. Lastly, we need to find the square root of both sides. the square root of a^2 is a, and the square root of 81 is 9. which leaves us with a = 9

The equation in slope-intercept is   y=0.625x+7.    


y = mx + b

where: 
m is the slope of the line 
b is the y-intercept of the line

The slope m of the line through any two points (x1, y1) and (x2, y2) is given by:

The y-intercept b of the line is the value of y at the point where the line crosses the y axis. Since for point (x1, y1) we have y1 = mx1 + b, the y-intercept b can be calculated by:

b = y1 - mx<span>1.    hope that helped</span>
