Answer:
A. <u>Volume = 4,523.9 mm³ (cubic mm)</u>
B. <u>Surface area = 1,658.76 mm² (square mm)</u>
Step-by-step explanation:
A. Lest's calculate the volume of the cylinder:
r = 12 mm, h = 10 mm
Volume = π * r² * h
Volume = 3.1416 * 12² * 10
Volume = 3.1416 * 144 * 10
<u>Volume = 4,523.9 mm³</u>
B. Let's calculate the surface area of the cylinder:
Surface area = 2π * r * h +2π * r²
Surface area =2π * 12 * 10 + 2π * 12²
Surface area = 6.2832 * 120 + 6.2832 * 144
<u>Surface area = 753.98 + 904.78 = 1,658.76 mm²</u>
The radius is 6
Complete the square on the equation and get
(x-6)^2 + (y-6)^2 =36
The circle equation is
(x-h)^2 + (y-k)^2 = r^2
Center(h,k) r=radius
Answer:
Reflect over the y-axis
Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis.
The reflection of the point (x,y) across
the y-axis is the point (-x,y).
