Answer:
cylinder has greatest volume
Step-by-step explanation:
solution
given,
radius of cylinder(r)=6cm
height of cylinder (h)=6cm
we know,
volume of cylinder=πr^2h
=22÷7×6×6×6
=4752÷7
=678.857cm^3
radius of cone(r)=6cm
height of cone(h)=12cm
we know,
volume of cone=1÷3πr^3
= 1÷3×22÷7×6×6×6
= 4752÷21
=226.2857cm^3
as a result,cylinder has greatest volume
19. Answer: 3p^6
Working:
3p^4 x p^2 = 3p^6
(Formula: a^b x a^c = a^b+c)
20.Answer: 42z^8
7z^5 x 6z^3 = 42z^8
(Same formula as Q19)
7. Answer: a^-4 or 1/a^4
a^3 / a^7 = a^-4
(Formula: a^b / a^c = a^b-c)
8. Answer: j^-1 or 1/j
(Same as Q7)
9. Answer: 1
(Same as Q7)
(x^0 = 1)
10. Answer: k^-4
(Same as Q7)
11. Answer: 3x^3/4
(Same as Q7)
(9/12 = 3/4)
12. Answer: 2f^5
13. Answer: (y^8)/2
(Same as Q7)
(4 - (-4)) = (4 + 4)
14. Answer: 1/n^5
(negative power = 1/power)
Sorry got no more time sorry
Answer:
4p
Step-by-step explanation:
To simplify this expression, just add/subtract as normal.
3p + 2p - p
3p + 2p = 5p
5p - (1)p = 4p
4p is the simplified version of 3p + 2p - p.
Answer:
3(n - 7) = 18
Step-by-step explanation:
three times the difference of a number and 7 is 18
three times the difference of a number and 7 = 18
three times (n - 7) = 18
3(n - 7) = 18
