help 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 = 2 units and s = 3 units, write an expression that can be used to calculate the surface area of the cone. (4 points)

Write the expression 7x^3-28xy^2 as the product of 3 factors

Identify this conic section. x2 - y2 = 16 o line circle ellipse parabola hyperbola

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
