Which measurement is most accurate to describe the width of a penny?
klasskru [66]

Answer:

19 mm

Step-by-step explanation:

A penny is not that large, and you can fit multiple pennies in the palm of your hand. This means that the only reasonable measurement is 19 mm, (& 8 cm, but that is only if you have really large hands). Therefore, (A) is your choice.

A cone has a radius of 11 inches and a height of 4.5 inches. What is the volume of the cone to the nearest tenth in³ ? Use 3.14
postnew [5]
Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
r = 11
h = 4.5
π ≈ 3.14
(1/3) (3.14) (11²) (4.5) = 
(1/3) (3.14) (121) (4.5) = 
(1/3) (3.14) (544.5) = 
(1/3) (1709.73) = 569.91

569.91 rounded to the nearest tenth is 569.9 so your answer would be 569.9 in³
