Multiple choice

Curved surface area of a right circular cylinder is $4.4$ $\displaystyle m^{2}$ If the radius of the base of the cylinder is $0.7$ m then its height is

  1. $2$ m
  2. $3$ m
  3. $4 $m
  4. $1$ m

D Correct answer
Explanation

Curved surface area = 2 * pi * r * h = 4.4. 2 * (22/7) * 0.7 * h = 4.4. 4.4 * h = 4.4, so h = 1.

AI explanation

The formula for the curved surface area of a cylinder is 2 * pi * r * h, where r is the radius and h is the height. We rearrange the formula to solve for the height: h = Curved Surface Area / (2 * pi * r). Substituting the given values results in 4.4 / (2 * (22 / 7) * 0.7), which simplifies to 4.4 / 4.4, giving a height of 1 m.
