Volume of sphere = 4/3 x pi x r^3
Volume of large sphere:
4/3 x 3.14 x 14^3 = 11488.21 cubic cm
Volume of smaller sphere:
4/3 x 3.14 x 2^3 = 33.49 cubic cm
Number of small spheres = volume of large sphere/ volume of small sphere
11488.21 / 33.49 = 343.03
Round to 343 small spheres
C=10, C=90°, B=30°, A+B+C=180°
A+30°+90°=180°⇒A=60°
cos30°=a/c
cos30°=a/10⇒a=cos30°*10
a<span>≃8.6602
c²=a²+b²⇒b²=c²-a²
b²=10²-8.6602²⇒b²=25
b=5

Here,
Principal = 600000
Rate = 10%
Time = 2.5 years
Simple Interest = ?
Amount = ?
Now,
Simple Interest = (P*T*R)/100
= (600000*2.5*10)/100
= 150000
Amount = Principal + Interest
= 600000 + 150000
= 750000
I hope you understand...
It is a Right answer...
Thanks♥♥
Y=40 I believe this is the answer
