Answer:
You have not given any detail about the cylinder like radius diameter or height.
To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lw
A=(5)(5)
A=25 cm²
Area of triangle=1/2bh
A=(1/2)(5)(12.5)
A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25
SA=125+25
SA=150 cm²
Answer:
t = 5 or t = 0
Step-by-step explanation:
Solve for t:
12 t (t - 5) = 0
Divide both sides by 12:
t (t - 5) = 0
Split into two equations:
t - 5 = 0 or t = 0
Add 5 to both sides:
Answer: t = 5 or t = 0
