A sundae with 1 topping is $0.99, with 4 toppings is $1.74, and with 7 toppings is $2.49. Which equation represents the cost of the sundae, c, given number of toppings, r?

answer: what

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

tube or goog would be a great resource to with that question
