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!
Answer:
140
Step-by-step explanation:
7×20=140 & 7×4=28 that is why
In the question , the length of the actual rope is given as 40 foot. Also it is given that the length of one rope after cutting the original piece of rope into 2 pieces is 9 times that of the other pice.
Let us assume that the length of one piece of rope is = X
Then the length of the orther pice of rope = 9X
Now we can easily get the equation
X + 9X = 40
10X = 40
X = 40/10
X = 4
So the length of the shorter rope is 4 foot.
The length of the longer rope is 9 times that of the shorter one.
So the length of the longer rope is 36 foot.
The circle can be cut into pieces, separated, and fit together to form a parallelogram that has the same area. The height of the parallelogram is the radius and the base is half the circumference, which is r. The area is r(r), which is equal to r2.
