The volume of a cylinder is given by the formula;
Volume = πr²h, where r is the radius, and h is the height or the length
Therefore,
252 π cm³ = π r² (7)
r² = 252/7
= 36
r = √36
= 6 cm .
Hence, the radius of the cylinder is 6 cm
Answer:
17
Step-by-step explanation:
Saying 25+ -8 is basically saying 25-8, and since 25 is the bigger number and it's positive, you get positive 17
Rileyflipflop,
= 8
, since she can't buy half a CD, she's limited to no more than 8 CDs. If x = the cost of one CD, then x CDs cost $18x. Since we are limited to $153, our equation looks like... 18x < 153x < 8
Again, since we can't buy half a CD, your answer should actually be... x ≤ 8 since we can buy 8 CDs or fewer.
First restaurant price: 29 + 6l = x
x = final cost
l = kilo of lobster
Second restaurant price: 41 + 3l = x
We want them to be the same price, so: 29 + 6l = 41 + 3l
Subtract 3l from each side
29 + 3l = 41
Subtract 29 from both sides
3l = 12
Divide both sides by 3
l = 4
So, if she buys 4 kilograms of lobster from either place, it will cost the same.
It would cost $53.
Answer:
shaded area = total area - the two triangles areas
total area = 5*9 = 45 cm²
first tri area = 1/2 * h *b
= 0.5 * 5 * 2 = 5 cm²
second tri area = 0.5 * 6 * 5 = 15 cm²
shaded area = 45 - 15 - 5 = 25 cm²
