Answer:

The height of the cone is 10.9 cm

Step-by-step explanation:

step 1

Find the height of the cone

Applying the Pythagoras Theorem

12^{2}=5^{2}+h^{2}

144=25+h^{2}

h^{2}=144-25

h^{2}=119

h=10.9\ cm

therefore

The height of the cone is 10.9 cm

3 times what gives me a sum of 24? im trying to finish my homework so please help.
Leno4ka [110]
It is not a sum, it is a product.

3 times x = 24   (write equation)
           3x = 24  (isolate x by dividing the coefficient, 3, on both sides)
           /3     /3
             x = 8    (this i your answer)

Therefore 3 times 8 gives you 24.
