Hello!
To find the area, we use the formula A=pir², where pi=3.14 and r= the radius.
To solve, we find half of the diameter, which is the radius. Half of 53 is 26.5. We square this number and then multiply it by pi. 26.5·26.5=702.25. Now we multiply by pi. 702.25·3.14=2,205.065.
Our final answer is about 2,205.1 cm².
I hope this helps!
The answer would be x=180-65 this is because vertically opposite angle to 65 would be 65 which means that x and 65 are supplementary.

Multiply the length*width*height to get the volume of the prism then, take out the difference between the volumes
Volume of the prism= 1018464
Then just subtract
5.1 • 0.79 = 4.029
