Acone shaped hat is shown:

what is the approximate height of the hat?

a: 2.79 centimeters, because height = square root of the difference of 14 and 6.2
b: 4.49 centimeters, because height = square root of the sum of 14 and 6.2
c: 12.55 centimeters, because height = square root of the difference of squares of 14
and 6.2
d: 15.31 centimeters, because height = square root of the sum of the squares of 14 and
6.2

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,

⇒

⇒

⇒

Hence, Option C is correct.

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
