What is the volu ne of the cylinder? Use 3.14 for it, and round your answer to the nearest tenth. 12 ft
5 ft

942

Step-by-step explanation:

If 5 is the radius and 12 is the height, and the formula of a cylinder is  V=πr^2h, we can substitute.

V=π(5)^2(12)

5^2 is 25, and 25 times 12 is 300.

300π, and that would be approximately 942.

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
