Answer:
32 pi m^2
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2pi r^2 + 2 pi rh
The diameter is 4 meters so the radius is 1/2 of the diameter = d/2 = 2 meters
SA = 2 * pi * (2)^2 + 2 pi *2*6
= 8pi +24pi
= 32 pi m^2
(This is an English question) but it would mean A.history

Answer:
1/16 meters
Step-by-step explanation:
perimeter of a square = 4 x length of each side,
so the length of each side is (1/4)/4 = 1/16 meters
Anne will walk a distance of 7 km, and she takes 2 hours to walk that distance.
<h3>
For how long will Anne walk?</h3>
The total distance is 18.5 km.
She travels 10km by train and 1.5km by bus, for a total of 11.5km.
The distance that she walks is given by:
18.5km - 11.5km = 7km
So she walks for a distance of 7 km, at a speed of 3.5km per hour.
Remember the relation:
distance = time*speed
That can be rewritten to:
time = distance/speed.
Then the time that she walks is given by:
T = (7 km)/(3.5 km/hour) = 2 hours
She walks for 2 hours.

35<em>x</em>² = 7<em>x</em> • 5<em>x</em>, and
5<em>x</em> (7<em>x</em> + 3) = 35<em>x</em>² + 15<em>x</em>
Subtract this from the dividend to get an initial remainder of
(35<em>x</em>² - 48<em>x</em> - 27) - (35<em>x</em>² + 15<em>x</em>) = -63<em>x</em> - 27
-63<em>x</em> = 7<em>x</em> • (-9), and
-9 (7<em>x</em> + 3) = -63<em>x</em> - 27
Subtract this from the previous remainder to get a new one of
(-63<em>x</em> - 27) - (-63<em>x</em> - 27) = 0
and we're done.
Now just gather the terms in bold (and the remainder, but since it's 0 we leave it out). So we have
(35<em>x</em>² - 48<em>x</em> - 27) / (7<em>x</em> + 3) = 5<em>x</em> - (63<em>x</em> + 27) / (7<em>x</em> + 3)
(35<em>x</em>² - 48<em>x</em> - 27) / (7<em>x</em> + 3) = 5<em>x</em> - 9
