Answer:
5
Step-by-step explanation:
To obtain the total score for all the 20 students, we multiply the average score by the number hence
Total score for all 20 is 81*20=1620
Similarly, for the 19 students, the sum of their total score equals the product of the average and number of students hence
Total score for 19 readable is 19*85=1615
The difference between these two total scores ie for 20 and 19 students equals to the value of unreadable score. Therefore,
Difference=1620-1615=5
Therefore, the value of unreadable score is 5
Answer: Volume of the cone = 47.12 cubic feet.
Step-by-step explanation:
You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.
To solve for the full volume including the cylinder, use the cylinder's volume formula.
Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.
Volume of a cone is pi(r^2)(h/3)
plug and chug!
h stands for height and r stands for radius.
S = 2 (lw + lh + hw)
S = 2 ((8.5)(11) + (8.5)(2) + (11)(2))
S = 2 (93.5 + 17 + 22)
S = 2 (132.5)
S = 265 sq in
Answer:
Yes
Step-by-step explanation:
2 yards = 72 inches
3 ft = 36 inches
72 - 36 = 36
She still needs 36 inches of fabric.
