Answer:
d)96π
Step-by-step explanation:
Given:
Cyliner with radius,a= 4
Height b=8
Surface area of cylinder, A=2πrh+2πr^2
=2π(rh+r^2)
=2π(4(8) + 4^2)
= 2π(32+16)
=2π(48)
=96π !

Answer:
3/14
Step-by-step explanation:
The answer is expressions D, E, and G.
In algebra, a ‘term’ usually means the different parts of an expression that are separated by + and - signs.
Options A and B only have 1 term, an x or y³, so these are incorrect.
Option C has 1 term as well, ‘xyz’, because they are all multiplied together which makes it one term.
D and E both have 3 terms each, but F has 4 unique terms so this is incorrect also.
G has 3 unique terms, x³, x^4, and 7x, so this is correct.
When H is expanded, you will end up with more than 3 unique terms, so this is incorrect.
I hope this helps!
Area of larger circle: 3.14 x 5^2 = 78.5
Area of small circle: 3.14 x 2^2 = 12.56
Difference of the 2 areas: 78.5 - 12.56 = 65.94
Probability of being in large circle but not small circle: 65.94 / 78.5 = 0.84 = 84%
The answer is A) 84%
