The base of a cone has a raidus 3.5cm long find the distance round the base of the cone take π =22/7
The formula for finding the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.
In this case, the radius of the cone's base is 3.5 cm. Plugging this value into the formula, we get:
C = 2π(3.5)
C ≈ 2 * (22/7) * 3.5
C ≈ 22 cm
Therefore, the distance around the base of the cone is approximately 22 cm.
