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:
200
Step-by-step explanation:
Steps
6.6 x 10^{-2}/3.3 x 10-4
10^{-2}-4(-4) x 6.6/3.3
10^{-2} x 6.6 = 660/3.3
=200
Answer:
The turning point of a parabola is the vertex
Vertex form of a quadratic equation: 
(where (h, k) is the vertex and a is the coefficient of the variable x²)
Given:

- vertex = (-1, 3)
Therefore, a = 1
Substituting a = 1 and the given vertex into the equation:




Therefore, a = 2 and b = 4
