Answer:

356.8cm3

Step-by-step explanation:

Volume of a cone= 1/3 * base area * height.

Note: don't be confused by right circular cone ; a cone is gotten from a cylinder by dividing it into three parts. One from the right vertex slanted to the middle of the base; another from the left vertex slanted to the middle of the base and the remaining portion with the surface base at the top.

Going forward; base area =pi * raduis * raduis [ area of a circle; the base is a circle]

Volume= 1/3 * (3.142 * 7.8 * 7.8 *5.6) = 356.83cm3

Volume= 356.8cm3 [ to the nearest tenth].

Tenth means 1/10= 0.1; that is value after the decimal point.

Answer:

<u><em>24,501.42 m³</em></u>

Step-by-step explanation:

Volume (cylinder) = πr²h

r = d/2 = 34/2 = 17 m

h = 27 m

V = 3.14 x 17 x 17 x 27

= 53.38 x 459

= <u><em>24,501.42 m³</em></u>

Answer:

Option C

Step-by-step explanation:

complete question

A. 35[3]6cB. 12[3]12cC. 12[3]6cD.72c

The given equation can be written as

5^3√6c+7^3√6c

5 * \sqrt{3 *3*2c} + 7 * \sqrt{3 *3*2c}

5 * 3 *\sqrt{2c} + 7 * 3  *\sqrt{2c}

15  *\sqrt{2c} + 21 *\sqrt{2c}

36 *\sqrt{2c}

12 [3]*\sqrt{2c}

Option C is correct
