Answer:6.928
Step-by-step explanation: formula A=√ 3*(side^2/4)
Answer:
24 tests
Step-by-step explanation:
Since 32 equals one hour and one hour is the total, we can see that 15 minutes equal 1/4, or 25%, 30 minutes equal 2/4, or 50%, and 45 minutes equal 3/4, or 75%. So, we can divide 32 by 4 to find out 1/4, or 25%, which equals 8. You can then multiply 8 by the number of fourths in 75% or 45 minutes, which is 3. 8 x 3 equals 24, so Mrs. Wilbur can grade 24 tests in 45 minutes.

<span>Cone Volume = (PI * 8^2 * 13.5) / 3
</span><span>Cone Volume = (3.14 * 64 * 13.5) / 3
</span>Cone Volume = 2,712.96 / 3
Cone Volume = 904.32 cubic feet
<span>Cone Volume = 904 cubic feet (rounded)

The dividend is 2
since 2 times 12 equals to 24
