Lelu [443]

Answer:

1156.8cm^3

Step-by-step explanation:

The volume of a cone is given as:

V =\frac{1}{3}  \pi r^2h

where r = radius

h = height of cone

The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).

Its volume is:

V = \frac{1}{3} * \pi = 7.9^2 * 17.7\\ \\V = 1156.8cm^3

2x + 4y =450 4x + 2y = 420​
masya89 [10]

2x+4y=450

2x=450-4y

x=450-4y÷2----- equation 1

4x+2y=420

4x=420-2y

x=420-2y÷4----- equation 2

putting the value of x in equation 1

x=450-4y÷2

420-2y÷4=450-4y÷2

2(420-2y)=4(450-4y)

840-4y=1800-16y

840-1800=-16y-4y

-960= -12y

y=80

putting the value of y in equation1

2x+4y=450

2x+4×80=450

2x+320=450

2x=450-320

2x=130

x=130÷2

x=65

<h2> the value of x is 65 and y is 80</h2>
