Answer:

Lateral area =

pi * (radius) * √ [ height ^2 + radius^2 ] =

pi * ( 4 ) * √ [ 4^2 + 3^2 ] =

pi * ( 4 ) * √25 =

pi * ( 4 ) * (5 ) =

20 pi units^2 ≈ 62.8 units^2

9.4 × $10^{2}$

1) Move the decimal point 2 times to left in the number so that number, 940 so it's between 1-10: 9.4 or 9.40

2) After we moved our decimal point to the left, the decimal count would be 12 and that we moved 2 places to the left

3) We know that the notation is a x $10^{b}$

a=9.4 and 6=2

9.4 × $10^{2}$ =a x $10^{b}$

I hope I've helped!

$log_{4}x = k \\ \\ \longrightarrow \: log_{4}x = log_{2 {}^{2} }x \\ \\ \longrightarrow \: 2 log_{2}x \\ \\ now , \\ \\ log_{2}x = k \\ \\ \therefore \: 2( log_{2}x) = 2(k) \\ \\ \longrightarrow \: 2k$

F(x)=8
3x+2=8
-2 both sides
3x=6
Divide 3 both sides
