Answer:
464 π in²
Step-by-step explanation:
The smallest circle has a radius of 8 in.
The middle circle has a radius of 8 + 4 = 12 in.
The largest circle has a radius of 12 + 4 = 16 in.
So the sum of the areas is:
π (8 in)² + π (12 in)² + π (16 in)²
= 64π in² + 144π in² + 256π in²
= 464π in²
Step-by-step explanation:
Average speed (S) = 200 m/s
Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec
Now distance travelled (d) = ?
We know
The distance travelled by a body per unit time is
speed so
S = d / t
200 = d / 9000
d = 9000 * 200
d = 1800000 meters.
The plane flies 1800000 meters.
