Not sure what you are asking. "55.34524" IS expressed numerically.
85,000,000,000.00
200,000,000
I think you just did.
165,100,000,000.
10,614,000,000
7,000,000
It is: 245,510,000,000
1,100
1000*1000 = 1,000,000. or, one million.
1,244,000,000 or 1.244 x 109 or to keep it 1224 million you can express it as: 1224 x 106
You can write it numerically like that or express it in kanji (八十六 / hachijyuuroku).
Because of the cylinder's circular shape, its surface area includes a multiple of pi. Because pi is an irrational number, you can not express its exact value numerically. The fact that you can't express it numerically does not however mean that you can't express it at all. For example, a cylinder with a radius of 1 centimeter and a height of 1 centimeter will have a surface area of exactly 4π centimeters.
