Answer:
A=2πrh+2πr2 this is the surface are formula of a cylinder. You already know the scale ratio is 2.5 so the answer is (2.5*surface area formula). For the formula just plug in the values for the radius and the height that is given and solve.
Step-by-step explanation:
Answer:
The next three terms are 54, 162, 486
Step-by-step explanation:
Exponential sequences you multiply to find the next term
6 x 3 = 18 (to find the next term you can multiply the previous term by 3)
18 x 3 = 54
54 x 3 = 162
162 x 3 = 486
Answer:
2-\sqrt{3} \\
Step-by-step explanation:
2-\sqrt{3} \\
Answer:
the first one
Step-by-step explanation:
because 4/6=2/3
2/3=6/9
so 4/6=6/9
