Answer:

The answer is actually <em>33.5 </em>(Apologies for the late answer)

Step-by-step explanation:

The below answer forgot the fact that the diameter is 2 times the radius, so they multiplied the cube of the diameter instead of the cube of the radius. By these means, the problem comes out like so:

                                                V=\frac{4}{3}(\pi)(r^3)

                                                V = \frac{4}{3}(3.14)(2^3)\\\\V=\frac{4}{3}(3.14)(8)\\\\V=\frac{4}{3}(25.12)\\\\V=\frac{100.48}{3}\\\\V=33.493333...\\

And now the problem wished for us to round the volume to the nearest tenth, so we must round up 33.493333... to <em>33.5 cubic centimeters.</em>

The volume of a sphere refers to the number of cubic units that will exactly fill a sphere. The volume of a sphere can be found or calculate by using the formula V=4/3πr^3, where r represents the radius of the figure.

In this exercise is given that a sphere has a radius of 4 centimeters and it is asked to find its volume and use 3.14 as the value of π or pi. The first step would be substitute the values into the previous mention formula.

V=4/3πr^3
V=4/3(3.14)(4 cm)^3
V=4/3)(3.14)(64 cm^3)
V=267.9 cm^3
The volume of the sphere is 267.9 cubic centimeters.

Write an equation or system of equations to solve the problem below.
VashaNatasha [74]

Equations:

2x+105=-3x+130

<em>subtract</em><em> </em><em>2x</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em>

<em>105</em><em>=</em><em> </em><em>-5x</em><em>+</em><em>130</em>

<em>Subtract</em><em> </em><em>130</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

<em>-5x</em><em>=</em><em> </em><em>-25</em>

<em>isolate</em><em> </em><em>the</em><em> </em><em>variable</em>
