Find the volume of the cone.
8_murik_8 [283]

Answer:

V=471\ \text{units}^3

Step-by-step explanation:

Given that,

Radius of the cone, r = 5 units

Height of the cone, h = 6 units

We need to find the volume of the cone. The formula for the volume of the cone is given by :

V=\pi r^2 h

Substitute all the values,

V=3.14\times 5^2\times 6\\\\V=471\ \text{units}^3

So, the volume of the cone is 471\ \text{units}^3.

Two smaller triangle have areas of 75 m square and 12 m squared. find the ratio of their perimeters
Paul [167]

we know that two similar triangles will have ratio corresponding side is same.

ratio triangle 1 is 75m^2.

and triangle 2 is 12m^2.

75:12=\frac{75}{12} =\frac{25}{4} .

so we have ratio of area 25:4.

ratio of perimeter will be \frac{25}{4} =\frac{50}{8} =\frac{25}{12}.

from these perimeter ratio also \frac{25}{4} =25:4.

Xác suất xảy ra môt sự kiện là 0.3. Xác suất để sự kiện đó không xảy ra là?
hodyreva [135]

Câu trả lời:

0,7

Giải thích từng bước:

Xác suất để một sự kiện xảy ra = 0,3

Cho sự kiện = A

P (A) = 0,3

Xác suất mà sự kiện không xảy ra có thể thu được bằng cách sử dụng quy tắc bổ sung;

P (A ') = 1 - P (A)

Vì thế,

P (A ') = 1 - 0,3 = 0,7
