Surface area of sphere is 
Step-by-step explanation:
We need to find the surface area of the sphere while we are given volume of sphere = 972π
The formula used to find surface area is:
We need to find radius of sphere
We are given Volume = 972π, using this volume we can find radius of sphere
The formula used to find volume is:
Putting values and finding r
Taking cube root on both sides
![\sqrt[3]{r^3}=\sqrt[3]{729}\\ r=9](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%3D%5Csqrt%5B3%5D%7B729%7D%5C%5C%20r%3D9)
So, Radius of sphere r=9
Now finding surface area:
So, surface area of sphere is

Answer:
<h2>The scale is 1 inch rep 4 feet or </h2><h2>1:4</h2>
Step-by-step explanation:
This problem is on ratios, the ratio of one quantity to another is a way to represent their relative size.
Moreso, the scale of a drawing tells us to what extent the drawing has been increased (maximized) or decresed (minimized)
now given that the actual dimention of the appartmentis 28ft wide
and on the drawing the apartment is 7 inches wide, we can see that the actual dimension has been reduced by a factor of 28/7= 4
hence the scale to represent this reduction is
1 inch to represent 4 feet
Answer:
1 1/4 cup of cheese
Step-by-step explanation:
.5+.75
First we must take the 4 to the other side: giving us -2x = 6.
Then we take the -2 to the other side:
X = 6/-2
X = -3
The distance between the two points would be the square root of 40. Hope this helped!
