and height 2 m.
Answers
Answer :
Solution :
Given :
- Area of base = 250 m².
- Height of cylinder ,h = 2m.
To Find :
- Volume of the cylinder
Lets solve
Area of base is given : 250m²
Volume of cylinder = πr²h
Now, put the values
Therefore,
Volume of the cylinder = 500m³

Answer:
Width of rectangle is 25 cm.
Step-by-step explanation:
Given :-
A wire bend in form of square of side 30 cm.
Then wire is again bend in form of rectangle of length 35 cm.
To find :-
Width of the rectangle.
Solution :-
Here, Concept is : If we are bending wire in form of square than again bending it in rectangle. Than, perimeter of square will equal to perimeter of rectangle because we are not increasing length of wire by one measure we are bending it in square and rectangular shape.
So,
Perimeter of square = 4 × side
⟶ Perimeter = 4 × 30
⟶ Perimeter = 120
Thus,
Perimeter of square is 120 cm.
According to concept, Perimeter of square and perimeter of rectangle are equal.
So, Perimeter of rectangle is 120 cm.
Let, Breadth or width or rectangle be x cm.
We know,
Perimeter of rectangle = 2(Length + Breadth)
⟶ 120 = 2×(35 + x)
⟶ 120 = 70 + 2x
\⟶ 120 - 70 = 2x
⟶ 50 = 2x
⟶ 50/2 = x
⟶ x = 25
We take, Width of rectangle be x.
Therefore,
Width of rectangle is 25 cm.
