LUCKY_DIMON [66]

Answer:

268.0 in²

Step-by-step explanation:

refer to attached graphic as reference

volume of cone, V = (1/3) πr²h

in our case, we are given r = 4" and h = 16"

substituting this into equation:

V = (1/3) πr²h

=  (1/3) ·(3.14) · (4)²· (16)

= 267.94667 in²

= 268.0 in² (nearest tenth)

A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times. What is the experimenta
mihalych1998 [28]
The experimental probability is

  (number of times it stopped over Sect. 2) / (total number of times you tried it)

Number of times it stopped in Section-2: 36

Total number of times you tried it:  (20 + 36 + 24)  =  80

Experimental probability of Section-2  =  36/80 = 9/20  =  45%
