Question

A cone shaped hat is shown:

Answer 1

Answer: C: 12.55 centimeters, because height = Square root of the difference of squares of 14  and 6.2

Step-by-step explanation:

Here the radius of the hat = 6.2 cm

And, the slant height of the hat = 14 cm

Since, By the Pythagoras theorem,

$(\text{Height})^2 = (\text{ Slant height})^2 -(\text{Radius})^2$

⇒ $(\text{Height})^2 = (14)^2 -(6.2)^2$

⇒ $(\text{Height})^2 = 196 - 38.44 = 157.56$

⇒ $\text{Height} = \sqrt{157.56}=12.5522906276\approx 12.55\text{ cm}$

Hence, Option C is correct.
