The rectangle is 15cm by 45cm
2(3x)+2(x)=120
6x+2x=120
8x=120
X=15
3(15)=45
b) The surface area is 564.5. Picture below.
4. Three possibilities.
Formula for volume of a cylinder: πr^2h
Formula for volume of sphere: 4/3πr^3
If the radius of the sphere is 1 inch than the volume is: 4.18879 or 4.19 rounded.
I used substitution on this website https://www.omnicalculator.com/math/volume
Just plug in the 4.18879 at the cylinder volume and put in a random number in the radius or height whichever you want then it'll give you the one you left blank. You'll find three possibilities for the radius and height of 4.18879 volume.
Answer:

Step-by-step explanation:
<em><u>SLOPE FORMULA:</u></em>

Y₂=(-15)
Y₁=(-16)
X₂=(-7)
X₁=19
Solve.

So, the slope is 1/26.
D) 72 units, you get this answer by adding up 15+15+22+20 units to get the perimeter.
Answer:
D
Step-by-step explanation:
if you were to chose c you would find that to negatives make a positive and the first negative has to be there so d would be the best possible answer
