Answer 2

Question:

The curved surface area of a right circular cylinder of height 14cm is 88cm². Find the diameter of the base of the cylinder.

Answer:

✰Given:

• Height of the right circular cylinder is 14cm.
• Curved Surface Area of right circular cylinder is 88cm².

✰To find:

• Diameter of the base of the cylinder.

✰Solution:

We know that radius of the base of the cylinder is ½ of diameter of the base of the cylinder.

Then,we put the value of r is 2d.

According to question:

∵Curved Surface Area of cylinder=2πrh.

∴ 88cm²=2×22/7×2d×14

$\bold{∴ {\frac{88 \times 7}{2 \times 22 \times 14 \times 2}= 2cm}}$

Then,diameter of base of right circular cylinder is 2cm.
