The standard baseball measures 2 11/16" in diameter. What is its volume (to the nearest hundredth)?

Answers

Answer:

$10.16$ inch³

Step-by-step explanation:

The shape of a baseball is sphere. Given that, the diameter of the baseball is $2(11)/(16)$ inches.

So radius will be,

$=(2(11)/(16))/(2)$

$=((43)/(16))/(2)$

$=(43)/(32)$ inches.

We know that, the volume of a sphere is,

$V_(sphere)=(4)/(3)\pi r^3$

$=(4)/(3)\pi \left((43)/(32)\right )^3$

$=10.163\appox =10.16$ inch³

if the diameter = 2+11/16 inches, radius=diameter/2= 1+11/32 inches

volume of a sphere is (4/3)pi*r^3 = 10.16

Which of the following functions best represents the graph? A. f(x) = x3 + x2 − 4x − 4

B. f(x) = x3 + x2 − x − 1

C. f(x) = x3 + 3x2 − 4x − 12

D. f(x) = x3 + 2x2 − 2x − 1

Answers

Answer:

B. f(x)=x³+x²-x-1

Step-by-step explanation:

The value of the graph f(x) shows that at x=1 and x=-1 must yield f(x)=0

which is true in case B.

A. f(1)=1+1-4-4= -6≠0

C. f(1)= 1+3-4-12=-12≠0

D. f(-1)= -1+2+2-1= 2≠0

Hence, option B is correct

i.e. f(x)= x³+x²-x-1

I believe the answer is B.
