If the diameter of a penny 19.05 millimeters and the width of each penny is 1.52 millimeters, what is the approximate volume of the roll of pennies? use 3.14 for and round your answer to the nearest tenth

V = 433.0

Step-by-step explanation:

Equation for cylinder volume is V = π(radius)²(height)

Find the radius (half of diameter):

19.05 mm / 2 = 9.525 mm

height is 1.52 mm

π = 3.14

V = 3.14 (9.525)² (1.52) = 433.0153

Answer to nearest tenth:

V = 433.0

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

whatever you can spend with $11.53 or under.
