Answer:

82.72m

Step-by-step explanation:

Volume = πr2h

= 3.142*7*7*14

= 2,155.41m³

Now that we hav the volume of earth, we go on to find the raduis of the spread

2155.41m³ = 3.142*r²*0.4

2155.41m³ = 1.26r²

r² = 1,710.64

r = 41.36m

Width = diameter = 2r = 82.72m

Solve for 3+y/2=-212

Lyrx [107]

You have the following equation:

$3+\frac{y}{2}=-212$

In order to solve the previous equation for y, proceed as follow:

3 + y/2 = -212 subtract 3 both sides

y/2 = -212 - 3 simplify right side

y/2 = -215 multiply by 2 both sides to cancel the denominator left side

y = -215(2)

y = -430

Hence, the solution for y in the given equation is y = -430
