Mathematics
1 answer:
grandymaker [24]3 years ago
5 0

Answer:

Step-by-step explanation:

A proportion is being directly related to something, meaning that there is just multiplication or division (just a coefficient in front of the x-coordinate, nothing more).

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra
luda_lava [24]
The surface area of a sphere is A = 4 \pi r^{2} and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0. 

For example, let us assign values.
Let A=90

A= 90*9 = 810

90 = 4 \pi   r^{2} &#10;&#10;    and    810 = 4 \pi  r ^{2}

the first r is 2.68 and the second r is 8.03

then, \frac{8.03}{2.68} = 2.99626  or rounded off to 3.
