Answer:
252 cm²
Step-by-step Explanation:
=>Given:
r = 4.9 cm, and h = 3.3 cm of a solid cylinder, π = 3.14
=> Required:
Total Surface Area (T.S.A) = 2πrh + 2πr²
T.S.A = 2*3.14*4.9*3.3 + 2*3.14*4.9²
= 101.5476 + 150.7828
= 252.3304
= 252 cm² (approximated)
Answer:
<h2><em><u>2a</u></em></h2>
Step-by-step explanation:
(a+b-c)-(b-a-c)
= a + b - c - b + a + c
= a + a + b - b - c + c
= <em><u>2a (Ans)</u></em>
Assuming the x stands for multiplication... follow the ordering rules:
First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:
3x16 - 36 + 4 - 6x4
Now do the multiplications:
48 - 36 + 4 - 24
The rest is just addition and subtraction
48 - 36 + 4 - 24 = -8
