Answer:
13,260.22 mm²
Step-by-step explanation:
the area of the shaded region is the area of the larger circle minus the area of the smaller one
to find the area of the larger we will use half of 62 plus 41 as the radius:
Area (larger) = 3.14(72)²
= 16,277.76
Area (smaller) = 3.14(31)²
= 3,017.54
Area (shaded region) is 16277.76 - 3017.54 = 13,260.22 mm²
Answer:
cos 30 + sin60 + sin30 - cos60
we know that sin ( 90 -a ) = cos a { and vice versa }
therefore by using this property,
sin ( 90 - 30 ) + sin 60 + sin 30 - sin ( 90-60)
sin 60 + sin 60 + sin 30 - sin 30 =
<u>2 sin 6</u><u>0</u>
That's the answer I got. Tell me if it's correct
Answer:
Height = 250km
Step-by-step explanation:
Given,
rate of rise of ballon 1 = 38 km/h
rate of rise of ballon 2 = 50 km/h
Let the time after which both the ballons will reach same height be 't'.
hence, after 't' hours,
⇒ height of ballon 1 = height of ballon 2
⇒ 38t + 60 = 50t
⇒ 12t = 60
⇒ t = 5 hours
so, the height at which both the ballons will be at the same height will be 250km.
