PilotLPTM [1.2K]

we are given

Sam packed 42 kg of rice

So, total amount of rice =42kg

And there are six small bags

each contains 1/10 of the rice

So, rice on each bags is

=\frac{1}{10}\times 42

=4.2kg

so, total rice in 6 bags is

=6\times 4.2kg

=25.2kg

so, the rice in big bag = ( total amount of rice )-( total rice in six small bags)

we can plug values

and we get

Answer:

Radius: 8

Circumference: 50.27

πr^2 = Area of circle

201.06 = πr^2

divide by pi

201.06 / π = 63.9993857161 = 64

64 = r^2

Square root both sides to get radius.

\sqrt{64} = 8

r = 8

Circumference = π x diameter

Diameter = 2 x radius

Circumference = π x 16 = 50.2654824574 = 50.27
