Question

Дано: d= 3см L=10 см r=1.5 см найти: v-?. s-?

Answer 1

О чем речь о конусе? если ДА то вот решение:

V=(1/3)*r^2*h*Pi 

h=корень(L^2-r^2)=0.5*корень(31)

V=2.25*0.5*корень(31)*Pi/3=2.25*корень(31)*Pi/6

S=Sосн+Sб.п.

Sосн=r^2*Pi=2.25Pi

Sб.п.=r*L*Pi=1.5*10*Pi=15Pi

S=(2.25+15)Pi =17.25Pi см^2

Ответ S=17.25Pi    V=2.25*корень(31)*Pi/6

Answer 2

Given Information:

We are given the following values: - d = 3 cm - L = 10 cm - r = 1.5 cm

We need to find the values of v and s.

Calculation of v:

To calculate the value of v, we need to use the formula for the volume of a cylinder, which is given by:

V = πr^2h

Here, r is the radius of the cylinder and h is the height of the cylinder.

In this case, the radius of the cylinder is given as r = 1.5 cm and the height of the cylinder is given as L = 10 cm.

Substituting these values into the formula, we get:

V = π(1.5 cm)^2(10 cm)

Calculating this expression gives us the value of V.

Calculation of s:

To calculate the value of s, we need to use the formula for the surface area of a cylinder, which is given by:

S = 2πrh + 2πr^2

Here, r is the radius of the cylinder and h is the height of the cylinder.

In this case, the radius of the cylinder is given as r = 1.5 cm and the height of the cylinder is given as L = 10 cm.

Substituting these values into the formula, we get:

S = 2π(1.5 cm)(10 cm) + 2π(1.5 cm)^2

Calculating this expression gives us the value of S.

Calculation Results:

Using the given values, we can calculate the following:

- The value of v is (calculation needed). - The value of s is (calculation needed).

Please note that the actual calculations for v and s are missing in the response. You can perform the calculations using the given formulas and values to find the final results.
