What is the volume of a sphere with a diameter of 6 m, rounded to the nearest tenth of a cubic meter?
seraphim [82]

Answer:113 cubic meter

Step-by-step explanation:

Diameter=6

Radius=r=6/2

Radius=r=3

π=3.14

Volume of sphere=4/3 x π x r x r x r

Volume of sphere=4/3 x 3.14 x 3 x 3 x 3

Volume of sphere=(4x3.14x3x3x3) ➗ 3

Volume of sphere=339.12 ➗ 3

Volume of sphere=113.04

Volume of sphere =113 cubic meter

KengaRu [80]

Answer:


Step-by-step explanation:

x + y = 25 ...........................(1)

{4x + 2y  =64} / 2    divide the equation by 2

2x + y = 32 ........................(3)

Step Two

subtract (1) from (3)

2x + y = 32

x   + y = 25

x = 7

Therefore from equation 1 we get x + y =  25

but x = 7

7 + y = 25       Subtract 7 from both sides.

y = 25 - 7

y = 18

Check

4*x + 2*y =  64

4*7 + 2*18 =? 64

28 + 36 = ? 64

64 = 64

The checks out to be the right answer.
