The second one.
Step-by-step explanation:
Answer:
<h2>2.01 cm</h2>
Step-by-step explanation:
The formula of a volume of a sphere:

<em>R</em><em> - radius</em>
<em />
We have

Substitute:
<em>multiply both sides by 3</em>

<em>divide both sides by 4</em>

<em>divide both sides by π</em>

<em>use π ≈ 3.14</em>

Answer:
The total surface area of this box is 62.14 square feet
Step-by-step explanation:
Given:
Length = 3.5 feet
Width = 2.2 feet
Height = 4.1 feet
To Find:
The Surface area of the prism = ?
Solution:
The box is the shape of rectangular prism
Then the surface area of the prism = 2(lh +hw +wl)
Where
l is the length
w is the width
h is the height
Substituting the values
The surface area of the prism =
The surface area of the prism = 2(14.35 + 9.02 + 7.7)
The surface area of the prism = 2(31.07)
The surface area of the prism = 62.14 square feet
The answer is: 454 miles. You have to divide 2951 miles by 6.5 hours so 2951/6.5=454.
