Answer:

Step-by-step explanation:

The midpoint is halfway, so if half the length is 14 then the full length is 28 (14 × 2 = 28)

Hope this helps!

Five spheres are being painted for a display at a store. If the diameter of each sphere is

ivanzaharov [21]

<h2>Hello!</h2>

The answer is:

The total area is:

$TotalArea=192.4cm^{2}$

To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.

We know that the diameter of each sphere is 7 centimeters, so, calculating we have:

Calculating the radius we have,

$diameter=2*radius\\\\radius=\frac{diameter}{2}=\frac{7cm}{2}=3.5cm$

Then, calculating the area, we have:

$Area=\pi radius^{2}$

$Area=\pi 3.5cm^{2}=38.49cm^{2}$

Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.

So, calculating we have:

$TotalArea=5*38.48cm^{2}=192.4cm^{2}$

Hence, the total area is:

$TotalArea=192.4cm^{2}$

Have a nice day!

PLEASE HELP WITHIN THE NEXT FEW MINUTES!

statuscvo [17]

Volume of a sphere can be found by using the formula V= $\frac{4}{3} \pi r^{3}$ where r is the radius of sphere.

Lianne drew a sphere with a radius of 7 in that is r= 7 in .she has written $\frac{\pi}{3}$ and need to find what should be multiplied in numerator with pi.

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

As r= 7 she needs to multiply numerator $4 r^{3} = 4 (7^{3)} =4(343) =1372$

The number to be multiplied is 1372.
