Answer:
52 in approx
Step-by-step explanation:
Given data
Length of TV= 42 in
Widht of TV= 31 in
Required
The diagonal of the TV
Applying the Pythagoras theorem
D^2= L^2+W^2
D= √L^2+W^2
D= √42^2+31^2
D=√1764+961
D=√2725
D=52.20 in
Hence the diagonal of the Tv is 52 in approx
Answer:
188π in^2
Step-by-step explanation:
Surface area of the rocket = surface area of the cone + surface area of the cylinder
Surface area of a cone = πr(r+h^2+r^2)
r = 8/2 = 4 in
4π( 4 + 3^2 + 4^2) =
4π ( 4 + 9 + 16) = 116π in^2
Surface area of a cylinder = 2πrh+2πr^2
(2 x n x 4 x 5) + (2 x n x 16)= 72π in^2
116 + 72 = 188π in^2
Answer:
300 students
Step-by-step explanation:
To know the number of students, we must divide the total amount of milk spent by the amount spent for each and in this way we will obtain the value we are looking for, like this (both have the same units of L, so there is no problem ):
30 / (1/10) = 300
that is to say that there are a total of 300 students
X/3=1351/7
cross multiply
7x=4053
divide by seven on both sides
x=579
