IOS converts a simple image into a circle, and ios image into a circle.
Push is a defined button.
Push. layer. masksToBounds = YES;
Push. layer. cornerRadius = 100;
Push. layer. borderWidth = 10;
Push. layer. borderColor = [[UIColor blackColor] CGColor];
1-11 is an expanded three-dimensional image. Its full area and volume (in centimeters) are easy to understand.
To restore the expansion chart, a cylinder with a radius of 10 and a height of 8 is cut to 3/4 (along the axis ), it is like splitting a circle of birthday cakes into four slices, one of which is taken.
Therefore, the surface area is: top and bottom area, 10 Circular Arc sides, 10 two sections
= Wu * r/4*2 + Wu * r * h/2 + r * h * 2
= 50-fold + 40-fold + 160
= 160 + 90 Cases
Volume = Wu r * h/4 = Wu * 10*10*8/4 = 200 Wu
It is not allowed to divide a circle into the following full equal graph numbers () A3 B5 C6 D7
D
The circle is 360 degrees a week. If the circle cannot be divided, it cannot be divided into full-level images.
If the output is D, the rest can be divisible.
