Answer:
-15x-4
Step-by-step explanation:
-21x + 6x-4
-15x-4
I’m sure that the area is 80. If you do 10 times 5, that will be 50.Then if you do 6 times 5, for the upper remaining part of the figure it would be 30. So 30 plus 50 is 50. Hope this helps!
<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.)
