Answer:
A = 7,241.2454026112 square mm.
or exact : A = 2,304.96*π sq mm
Step-by-step explanation:
Cylinder formula: A = π* r^2 + 2 *π * r* h + π*r^2
is the surface area.
d = 2r = 39.2 mm
h = 39.2 mm
r = 19.6 mm
A = π* r^2 + 2 *π * r* h + π*r^2
A = 2* π* (19.6)^2 + 2π (19.6)*(39.2)
A = 2,413.748467537 + 4,827.496935
A = 7,241.2454026112 square mm.
or
A = 2*pi* (768.32 + 384.16)
A = 2*1,152.48* pi
A = 2,304.96*π sq mm
Answer:
B.
Step-by-step explanation:
<2 and <3 are vertically opposite angles and are also congruent. Both the angles are hence called vertical angles.
Do you have answer options for this question?
Answer:
i'm guessing you're asking which expression is the same as 7(x+4)
i don't know what the other numbers listed are suppose to mean, but when expanded, 7(x+4)=7x+28
anything added together, multiplied together, etc, that equals 7x+28 is your answer
Since p is an obtuse angle
& that it's between two acute angles
