Answer:
2198 cm²
Step-by-step explanation:
Total surface area of a cylinder = 2πrh + 2πr²
Radius, r = diameter/2
= 20cm/2
= 10 cm
Height, h = 25 cm
Total surface area of a cylinder = 2πrh + 2πr²
= 2*3.14*10*25 + 2*3.14*10²
= 1,570 + 6.28*100
= 1,570 + 628
= 2198 cm²
Total surface area of a cylinder = 2,198 cm²
There are three terms in this polynomial, making it a trinomial. The terms are "abcd", "e", and "h^2".
The answer is b I did it on edge
1. Collect like terms
(n - 0.3n) + (4.5 - 3)
2. Simplify
0.7n + 1.5
Final Answer:
0.7n + 1.5
