Answer:
If 50.24cm = Circumference
Radius = 8cm
If 50.24cm^2 = Area
Radius = 4cm
Step-by-step explanation:
50.24cm what? Circumference? Area?
π = 3.14
2πr = Circumference
50.24 / 2π = r
r = 8
πr^2 = Area
50.24 / π = r^2
r^2 = 16
r = 4

Step-by-step explanation:
Sum of ratio : 9 + 7 + 4 = 20
a)
Adele share :
![\frac{9}{20} \times 680 = 9 \times 34 = \$ 306](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D%20%5Ctimes%20680%20%3D%209%20%5Ctimes%2034%20%3D%20%5C%24%20306)
b)
Barbara share :
![\frac{7}{20} \times 680 = 7 \times 34 =\$ 238](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B20%7D%20%5Ctimes%20680%20%3D%207%20%5Ctimes%2034%20%3D%5C%24%20238)
Collette share :
![\frac{4}{20} \times 680 = 4 \times 34 = \$ 136](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B20%7D%20%5Ctimes%20680%20%3D%204%20%5Ctimes%2034%20%3D%20%5C%24%20136)
c)
$ €
1.125 1
306 x
[cross multiply]
![x =\frac{ 306} {1.125}](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B%20306%7D%20%7B1.125%7D)
x = €272
Adele receives = €272
d)
Apple Cost
1 kg 2.69
5 kg y
y = 2.69 x 5 = $13.45
Cost of 5kg of apples = $13.45
Cost of 3 kg bananas = 17.56 - 13.45 = $4.11
Banana Cost
3kg 4.11
1 kg z
![z = \frac{4.11}{3}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B4.11%7D%7B3%7D)
z = $1.37
Cost per kilogram of banana = $1.37
e) Collette share = $136
Half of it on clothes = (1/2) x 136 = $68
(1/5) of her share on books = (1/5) x 136 = 27.20
Balance amount with her = 136 - 27.20 - 68 = $ 40.80
