A cartographer is painting a spherical globe whose surface is 326.7 sq. in. What is the maximum radius of the globe that the car

svlad2 [7]

Answer:

$S =4\pi r^2$

And since we know the surface area 326.7 in^2 we can solve for the value of r like this:

$r =\sqrt{\frac{S}{4 \pi}}$

And replacing we got:

$r =\sqrt{\frac{326.7 in^2}{4 (3.14)}}= 5.10 in$

And the best answer would be:

5.1 in

Step-by-step explanation:

For this case we need to use the formula for the surface area of a sphere given by:

$S =4\pi r^2$

And since we know the surface area 326.7 in^2 we can solve for the value of r like this:

$r =\sqrt{\frac{S}{4 \pi}}$

And replacing we got:

$r =\sqrt{\frac{326.7 in^2}{4 (3.14)}}= 5.10 in$

And the best answer would be:

5.1 in

The volumes of two similar solids are 729 inches3 and 125 inches3. If the surface area of the smaller solid is 74.32 inches2, wh

tangare [24]

This is the concept of scales factors, given that two similar solids with 729 inches^3 and 125 inches^3. The volume scale factor will be given by:
(volume of larger solid)/(volume of smaller solid)
=729/125
but
linear scale factor=(volume scale factor)^1/3
thus the linear scale factor will be:
(729/125)^1/3
=9/5
Also, area scale factor will be given by:
area scale factor=(linear scale factor)^2
=(9/5)^2
=81/25
The area of the larger solid will be given by:
let the area be A;
A/74.32=81/25
thus
A=81/25*74.32
A=240.7968 inches^2
