Circumference of a Circle,C=2πr

π=3.14
r= of the circle

Area of the circle= πr²

We know that
Area= 49 π²

πr²=49

r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units

Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units

Calculate the amount and the compound interest on Rs 12.000 in 2 years at 10%
mel-nik [20]

Answer:

Amount = p( 1+r/100) ^n

= 12000 ( 1+10/100) ²

= 12000( 10/10+1/10) ²

= 12000( 11/10) ²

= 12000 x 11/10 x 11/10

= 14520 rs.

Compund interest = amount - principal

= 14520 - 12000

= 2520rs.
