Two spheres have volumes of 8,cm and 647 cmIf the surface area of the smaller sphere is 16 cm?, what is the surface

Olegator [25]

Answer:

361.7cm²

Step-by-step explanation:

Volume of sphere 1= 8cm³

Volume of sphere 2 = 647cm³

But volume of sphere = 4/3πr³

The radius of sphere 2

647 = 4/3πr³

((3*647)/4)/π= r³

5.36544 = r

Surface area = 4πr²

Surface area for the big sphere

= 4π5.36544²

= 361.7cm²

Y = 6x + 11<br> 2х - Зу = 7

Answer:

(x, y) = (-2.5, -4)

Step-by-step explanation:

Since you are given an expression for y, it is convenient to substitute that into the second equation.

2x -3(6x +11) = 7

2x -18x -33 = 7

-16x = 40 . . . . . . add 33

x = -40/16 = -2.5

Using the equation for y, we find ...

y = 6(-2.5) +11 = -15 +11 = -4

The solution is (x, y) = (-2.5, -4).
