Answer:
a = 170
Step-by-step explanation:
0.3a = 51
a = 51 : 0.3
a = 51 : 3/10
a = 51 x 10/3
a = 510/3
a = 170
0.3x170 =
= 3/10x170
= 510/10
= 51
Answer:
0.02
Step-by-step explanation:
The Volume of cylinder is 3770 cubic millimeters
But, the correct option is not available in options given.
Step-by-step explanation:
Height of cylinder = 3mm
Diameter of cylinder = 40mm
Volume of cylinder = ?
The formula used to find Volume of cylinder is:

Putting values in the formula:
Since we need radius,
radius = diameter/2
radius = 40/2
radius = 20 mm
So,

The Volume of cylinder is 3770 cubic millimeters
But, the correct option is not available in options given.

Answer:
See below in bold.
Step-by-step explanation:
cos 150 = - cos(180 - 150)
= - cos 30
= -√3/2.
sin 150
= sin (180 - 150
= sin 30
= 1/2.
