This is the concept of areas of solid materials; the surface area of the cylinder whose radius is 2.5 cm and lateral area is 20 pi cm^2 will be: Surface area of cylinder is given by:
SA=(area of cyclic sides)+(lateral area)
SA=2πr^2+πrl
Area of the cyclic sides will be:
Area=2πr^2
=2*π*2.5^2
=12.5π cm^2
The lateral area is given by:
Area=20π cm^2
Therefore the surface area of cylinder will be:
SA=(12.5π+20π) cm^2
SA=32.5π cm^2
The answer is 32.5π cm^2
Answer:
what subject is this? or what
(you and 3 friends so we have 4 person
<span>The group plans to ride each water ride twice.</span>
so for each person we will pay 2(4.5+4+3.5)=2*12=24$
and for 4 person 24*4=96$
100-96=4$
Answer: 4$)
but looking on gaven answers i understood that each person pay only for himself!
so you paid 24$ and will get back 100-24=76$
Answer: 76$
