Answer:

OptionC

Step-by-step explanation:

A circle A has radius 6m.

One sector has area as 10 pi m^2

central angle = 100 degrees

Area of the sector = \frac{100}{360} \pi(6)^2

Area of sector in circle B = \frac{100}{360} \pi(r)^2

where r=radius of circle B

Hence ratio of these would be the ratio of square of radii

i.e.\frac{10}{40} =(\frac{6}{r} )^2\\\frac{1}{2} =\frac{6}{r} \\r=12 m

So radius of circle B = 12m

Option C is right

Helga [31]

Answer:

P (black marble) =3/11

Step-by-step explanation:

We need to find the total number of marbles

4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles

We take away a black marble and throw it away

3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles

The probability of drawing a black marble is

P (black marble) = black/total

                           =3/11
