What is the volume of a cone with a radius of 6 cm and a height of 12 cm? use 3.14 for pi. round your answer to the nearest hund
natima [27]
The answer is 452.16 cm³.
Formula to calculate the volume of cone = V = πr²x h/3
Now r = 6 cm and h = 12cm, and value of π = 3.14
By putting the values,
V = (3.14) (6)² (12/3) = (3.14)(36)(4) 
V = 452.16 cm³

15 POINTS!!!!!!! PLEASE HELP!! <br> Find the value of a. <br> A) 3 <br> B) 4 <br> C) 6 <br> D) 9
abruzzese [7]

Answer:

Step-by-step explanation:

The legs and hypotnuse of a triangle can easily be solved by using

A^{2} +B^{2} =C^{2}

with this in mind we can plug in the legs and hypotenuse of the triangle to solve for the missing leg, A.

A^{2} =C^{2} -B^{2} \\A = \sqrt{(5^{2} )-(4^{2}) } \\A=\sqrt{9} \\A=3

Hope this helps,

H.M.
