Hi!
Got a question!
1.The pie chart below shows the number of vehicles that passed along a road .
The number of buses was 45 . How many vehicles passed along the road?
A.424
B.234
C.324

C. 324

Step-by-step explanation:

first we shoulf find out what's the angle of buses first so :

360°- 150°- 96° - 64 °

= 50°

and we know that the number of buses is 45 so :

(45 × 360)/ 50 = 324

[why we should use 360° minus the other angles bcs 360° is the whole pie chart. ]

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
