Answer:
About 50.14 Centimeters
Step-by-step explanation:
The formula for the volume of a cylinder is:
Now, let's plug in the values. (We'll use 3.14 for pi.)
All we do now, is solve for r. Divide 76 on both sides...
Divide 3.14 on both sides...
Lastly, find the square root on both sides.
Therefore, the r, or the radius, is around 50.14 centimeters. Hope this helps!
8*6 and 24*2 and 3*16 and 12*4
Given:
Ratio of the side lengths of two similar rectangular prisms is .
To find:
The ratio of their areas.
Solution:
If two figures are similar then their areas are proportional to the squares of their corresponding sides.
...(i)
Where, are areas and are corresponding sides.
It is given that ratio of the side lengths of two similar rectangular prisms is . It means, .
Using (i), we get
Therefore, the ratio of their areas is . It is also written as 9:25.
Answer:
x²+y²-4x-6y+12.75=0
Step-by-step explanation:
The equation is given by (x-h)²+(y-k)²=r²
center is (2,3), so h=2, k=3,r=0.5
equation is given by;
(x-2)²+(y-3)²=0.5²
Expand
x(x-2)-2(x-2)+y(y-3)-3(y-3)=0.5²
4-2x-2x+x²+9-3y-3y+y²=0.25
4-4x+x²+9-6y+y²=0.25
x²-4x+13+y²-6y=0.25
x²-4x+y²-6y+13=0.25
x²-4x+y²-6y+12.75=0
x²+y²-4x-6y+12.75=0
