Answer:
The answer is option 5.
Step-by-step explanation:
The formula is V = 1/3×π×r²×h where r represnt radius and h is height. Given that the diameter of cone is 8 inches so the radius is 4 inches then substitute the value into the formula :
Let r = 4,
Let h = 12,
The values of the equation will be:
9. 12x - 1
10. -50 - x
11. -x + 14
12. x³ - 4y - 4
13. 8 - 6x
14. 288 - 1080x
15. 420 - y
16. 66 + 7y - 9x
<h3>How to compute the equation?</h3>
9. 4(3x+ 2) - 9
12x + 8 - 9
12x - 1
10. √144 – (62 –x)
12 - (62 - x)
-50 - x
11. (28 ÷ 4) – (x + 7)
7 - x + 7
= -x + 14
12. x³ – 4y - (6 + 2)
x³ - 4y - 4
13. 64 ÷ 8) – (x • 6)
= 8 - 6x
14. 72 (4 - 15x)
288 - 1080x
15. 4(√144 + 93)–y
4(12 + 93) - y
= 420 - y
16. 54 + 7y – (8 + 9x)
= 66 + 7y - 9x

Answer:
7.
Step-by-step explanation:
28 = 2^2 * 7.
To multiply 28 to get a perfect square, we can multiply it by 7 to get 2^2 * 7^2, which is 14 squared.
