Answer:

144.51326 cm^{2}

Step-by-step explanation:

A = 2πrh + 2πr^{2}

d = 4

r = 4/2 = 2 cm

h = 9.5cm

A = 2π(2)(9.5) + 2π(2)^{2}  = 144.51326 cm^{2}

Don't know if you need to round it or not

You know that
spayn [35]
So remember that percent means parts out of 100 so
52%=52/100=0.52

26%=26/100=0.26
'of' means multily

0.52 times x=65
divide both sides by 00.52
x=125




26% of a number is 39
0.26 times y=39
divide both sides by 0.26
y=150


x=125
y=150
y is greater


you know that becuase we know that 52% is exatly twice of 26% so therefor, if x=y then 52% of x is half of 26% of y so to compare them, we just divide the 65 number by 2 to find 26% of that number to get 65/2=32.5
32.5<39 so x is smaller number

Simplify 4sqrt(6) / sqrt(30) by rationalizing the denominator.
daser333 [38]
Given question is 4√6/√30
by rationalizing the denominator
4√6x√30/√30x√30
= 4√6x30/√30²
=4x√180/30 (i)
by solving the √180
√180=6√5
putting the value of √180 in (i)
=4x6√5/30
=24√5/30
=4√5/5 is the right answer.
