The surface area of a cone with radius r units and slant height s units is shown below: surface area = 3.14(rs + r2) part a: if r = 3 units and s = 5 units, write an expression that can be used to calculate the surface area of the cone. (4 points) part b: what is the surface area of the cone? show your work. (6 points)

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
