If my circumference is 163.28ft, what is my radius?

26 ft

Step-by-step explanation:

The circumference is given by

C = 2 * pi *r

163 .28 = 2 * 3.14 * r

163.28 = 6.28 r

Divide each side by 6.28

163.28/6.28 = 6.28r/6.28

26 =r

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
