Giving brainliest! A can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10 centimeters. Which measurement is donest to the total suratace area
of the can in square centimeters?

radiusr = 3 cm

heighth = 10 cm

volumeV = 282.743339 cm^3

lateral surface areaL = 188.495559 cm^2

top surface areaT = 28.2743339 cm^2

base surface areaB = 28.2743339 cm^2

total surface areaA = 245.044227 cm^2

In Terms of Pi π

volumeV = 90 π cm3

lateral surface areaL = 60 π cm^2

top surface areaT = 9 π cm^2

base surface areaB = 9 π cm^2

total surface areaA = 78 π cm^2

Step-by-step explanation:

Agenda:

r = radius

h = height

V = volume

L = lateral surface area

T = top surface area

B = base surface area

A = total surface area

π = pi = 3.1415926535898

√ = square root

Formluas:

Cylinder Formulas in terms of r and h:

Calculate volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**:

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
