Answer: D.) 200.96 in. cubed

Step-by-step explanation:

Volume Formula (Cone): V=(pi)r^2h/3

V=3.14(4^2)12/3

V=3.14(16)12/3

V=3.14(16)4

V=3.14(64)

V=200.96

Answer:

The volume of given cone is 602.88 cube units

Step-by-step explanation:

<u>Formula:</u>

Volume of cone, V = πr²h

r - Radius of cone

h - height of cone

<u>To find the volume</u>

Here, r = 4 and h = 12

Volume V = πr²h

V = 3.14 *4²*12

V = 3.14*4*4*12

Volume V = 602.88

Therefore the volume of given cone is 602.88 cube units

I round to 900 I have twice as many hundreds as ones and all my digits are different but their sums are 18 can someone answer th
stellarik [79]

Answer:

The number of once is 9.1  

The number of hundreds is 8.9

Step-by-step explanation:

Given as :

The total of digits having ones and hundreds = 900

The sum of digits = 18

Let The number of ones digit = O

And The number of hundreds digit = H

So, According to question

H + O = 18             .........1

100 × H + 1 × O = 900          ........2

Solving the equation

( 100 × H - H ) + ( O - O ) = 900 - 18

Or, 99 H + 0 = 882

Or , 99 H = 882

∴   H = \frac{882}{99}

I.e H = 8.9

Put the value of H in eq 1

So, O = 18 - H

I.e  O = 18 - 8.9

∴    O = 9.1

So, number of once = 9.1

number of hundreds = 8.9

Hence The number of once is 9.1  and The number of hundreds is 8.9
