Pi to the 5th power is approximately 306.019684785

Because the 2cm lens has 4 times the area of a 1cm lens. (area = Pi*r2)
-2 times -2 = plus 4 since minus times minus is plus
5 to the second power is read as 5 squared because it is 52 or 5 times 5 or 25. We call a square number for ex: 4 (2 times 2), 16 (4 times 4), et cetera. 8 is not a square number being that none of its factors are a number times itself.
Assuming pi to be 3.14, 2^2 = 4(120) = 480*3.14 = 1507.2
-4 to the second power is 16
4 times pi times 4 divided by 2 is 78.9568352087
The answer is 256.
Volume of a Sphere. Volume= (4/3)(pi)r^3 Multiple 4/3 times pi times the radius to the third power. The surface area of a Sphere is 4(pi)r^2
Volume = 4/3 times Pi times radius cubed (to the third power)
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
4,096 or 4 to the sixth power. When multiplying numbers with powers you add the powers if the whole number is identical. 4 squared x 4 squared is 64, x 4 squared is 4096

4^2 * 4^8= 16 * 65,536 = 1,048,576
