Answer:

V = 115.5 cubic yards

Step-by-step explanation:

V (cone) = 1/3πr²h

just substitute given values to get:

r = 7/2 or 3.5

h = 9

V = π(3.5²)(9)/3

V = 115.5 cubic yards

What is the greatest possible error if Bruce measured a buckle as 3.2 cm using the ruler?

IgorLugansk [536]

Answer:

The greatest possible error for the measurement 3.2 cm is 0.05 cm.

Step-by-step explanation:

We have given that,

Bruce measured a buckle as 3.2 cm using the ruler

We have to find,

What is the greatest possible error?

Solution is given by,

The greatest possible error is defined as the error is half of the measuring unit.

Bruce measured a buckle as 3.2 cm using the ruler.

The measuring unit is nearest tenth of a cm or 0.1 cm.

The greatest possible error is half of 0.1.

i.e. $GPE=\frac{0.1}{2}$

$GPE=0.05}$

Therefore, The greatest possible error for the measurement 3.2 cm is 0.05 cm.
