Answer:
Step-by-step explanation:
length of rectangle = circumference of circle = πd = 6π cm
area of rectangle = 2×6π = 12π cm
area of one circle = πr² = 9π cm²
surface area = 12π + 2(9π) = 30π ≅ 90 cm²

Answer:
The GCF for the variable part is
k
Step-by-step explanation:
Since

Answer:
3 4/5 or 3.8
Step-by-step explanation:
median you just start marking them off.
3 2/5, 3 2/5, 3 4/5, 3 4/5, 3 4/5, 4,4,4
Well, lets first start off with combining like terms.
9x + 26 + 7x - 17 = 2x + (-3x) + 5x
9x + 7x + will give you 16x, and 26 - 17 will give you 9. Therefore, the first part of the equation is 16x + 9.
On the other side, you can combine all three terms (2x + 5x - 3x), which will give you 4x.
Using the above steps, you can figure that the answer is 16x +9 = 4x
