Answer:
<h2>100πcm².</h2><h2>None of the options is correct</h2>
Step-by-step explanation:
Total surface area of a cone 
= 
Since the diagram is half of a cone, its surface area will be 
r = radius of the cone
l = slant height
From the diagram diameter of the cone = 16m;
r = 16/2 = 8m
l = 17m
Answer: B. 2=3x+10x^2
Step-by-step explanation:
The expression means the quadratic function equation.
B = 10x^2 + 3x -2 = 0
the equation is [-b ±√(b^2 -4ac)]/2a
b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
