Answer:
400
Step-by-step explanation:
first work out the radius of priya's circle with the equation a =



we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x
this means that if the diameter of dan's circle is 4 times bigger it must be
8x
to find the radius of dan's circle we divide the diameter by to 2 to give
4x 
then use the a=
equation again

which equals 400
hope that helped
The answer s=16 answer 48
Note that

in the given closed interval, so the area is exactly given by the definite integral

(no absolute values needed!)
Integrating gives
Answer:
YES
Step-by-step explanation:
PRIME NUMBER BETWEEN 10 & 20 ARE 11,13,17,19-four
We have 1 m = 100cm
⇒ 72 m = 7200 cm
⇒ 7200 / 1.5= 4800 cm = 48 m
