3 spheres of diameter 6cm,8cm and 10cm are melted to form a single sphere .find the diameter of the sphere.
julia-pushkina [17]

Answer:

Step-by-step explanation:

6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)

8/2= 4 cm is the radius and V = 4/3.π.64…..(2)

10/2=5 cm is the radius and V = 4/3.π.125…(3)

The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...

The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.

12 cms answer. Brainlist please?

T = K(1/H)

Whereas T = seconds

H = cooker setting

K = the constant of proportionality

Aliun [14]

Answer:

(-1.714, 1.857)

Step-by-step explanation:

Here, we want to find the approximate solution to the system of linear equations

We start by plotting the graph of the lines

We have the plot as shown below;

the red line represents the first equation while the blue line represents the second equation

We have the solution as the point at which the two lines meet

The solution to this is;
