Question

Vц= 98π см3, r=7см; h-?

Answer 1

Ответ:

h=2см

Объяснение:

Vц=πr²*h;

h=Vц/πr²=98π/7²π=98π/49π=2 сс

Answer 2

To find the value of h, we can use the formula for the volume of a cone:

V = (1/3) * π * r^2 * h

Given that V = 98π cm^3 and r = 7 cm, we can substitute these values into the formula:

98π = (1/3) * π * (7^2) * h

Simplifying the equation:

98 = (1/3) * 49 * h

Multiplying both sides by 3:

294 = 49h

Dividing both sides by 49:

6 = h

Therefore, the value of h is 6 cm.
