Answer:
easy peasy (again)
Step-by-step explanation:
given is that, area of the larger one is 25 times more than the smaller one
so, just put it in the area formula,
let the radius of the larger circle be represented by = R
and of the smaller circle be = r
then, (pi) (R)^2 =25 x (pi) (r)^2
=> dividing the equation by pi on both sides, also taking square root on both sides
=> R = 25 r
that would be the radius of the larger circle is 25 times bigger than the smaller radius
(all u need is to pay attention to the data given in the question and the relation between all that data itself) then it'll look like magic of how the question gets solved...the answer is always in front of you, only thing is to look harder ...good luck with what you are aiming to achieve
Answer:
Step-by-step explanation:
You need to know the formula for the area of a circle , do you?
it's pi*
plug in 1/2 of the diameter , they tell us it's 48 + 6 = 54
54/2 = 27
so
pi*
=2290.2 sq inches
Answer:
96 in²
Step-by-step explanation:
Lateral surface area
= 3 rectangles
(4×8) + (3×8) + (5×8)
32 + 24 + 40
96 in²
Answer:
R ≈ 8.31
Step-by-step explanation:
Filling in the given values ...
... pV = nRT
... 2·4.155 = 1·R·1
... 8.31 = R
