I’m getting 61/24 I’m sorry if it’s wrong.
Answer: B) -56i - 24
This is the same as -24 - 56i
=============================================
Explanation:
The 'i' refers to the imaginary number 
In other words, 
Squaring both sides gets us 
So,

The result is in the form a+bi where a = -24 is the real part and b = -56 is the imaginary part.

Answer:
85
Step-by-step explanation:
<h2><u>Solution</u> :-</h2>
Given : Radius of cylinder = 8 m
Height = 4 m
Volume of cylinder = πr²h cu. units
= 22/7 × 8 × 8 × 4 m³
= 804.57 m³ (approx.)
Curved surface area = 2πrh sq. units
= 2 × 22/7 × 8 × 4 m²
= 201.14 m² (approx.)
Total surface area = 2πr(r + h) sq. units
= 2 × 22/7 × 8 (8 + 4) m²
= 2 × 22/7 × 8 × 12 m²
= 603.43 (approx.)
