Tommy and ethan each ave a cylinder. tommy's cylinder as a diameter of 6.2 inches and a height of 8.8 inches. ethan cylinder as a diameter of 8.8 inches and a height of 6.2 inches . whose cylinder ads a larger total surface area?

Ethan's cylinder has a larger total surface area

Step-by-step explanation:

we know that

The surface area of a cylinder is equal to

step 1

Find the surface area of Tommy's cylinder

we have

----> the radius is half the diameter

substitute in the formula

step 2

Find the surface area of Ethan's cylinder

we have

----> the radius is half the diameter

substitute in the formula

Compare

therefore

Ethan's cylinder has a larger total surface area

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
