Answer:
solution:-
diameter of a cylinder (d) = 12 cm
length(h) = 30 cm
curved surface area of cylinder (csa) = ?
we know that ,
therefore , csa of cylinder = 2πrh
r = d/2
or, r = 12/2= 6 cm
Then, csa if cylinder = 2 ×22/7×30
= 2×22×30/7
= 1320/7
= 188.57 Square cm Ans,......
X=2 Y=-4.5 I got this by substituting the value of x into the equation 3(2y+7)-2y=3 and solving.
Answer:
22.05 pounds
Step-by-step explanation:
First, find the total mass in Kg.
We have four bags and they each weigh 2.5 Kg. Multiply the amount of bags by the weight of each bag. 4 bags x 2.5 Kg = 10 Kg of Cat food
Now, to convert from Kgs to Lbs, multiply the total weight by 2.205 (since one Kg is about 2.205 lbs)
10 Kg x 2.205 = 22.05 Lbs
That's a good amount of food for any cat

A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)
hoped this helped:)
