1 answer:

3 0

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

Repeat the following procedure for the four given numbers .

Volgvan

3
multiply by 4
12
add 12
24
divide by 2
12
subtract 6
6

number 6 : 6(4) = 24... + 12 = 36...36/2 = 18.....- 6 = 12
number 8 : 8(4) = 32....+ 12 = 44...44/2 = 22....- 6 = 16
number 12: 12(4) = 48....+ 12 = 60...60/2 = 30....-6 = 24

well...by following these steps, it appears the original number doubles as a result.
