Please help me I need to get this turned in now!!

Step-by-step explanation:

The radius of the circle is ( r = 4) so

$62.85

Step-by-step explanation:

Given data

ratio=  10: 7: 5

Total ratio= 10+7+5= 22

Lisa= $20

Her proportion of the ratio = 7

Applying the part to all method

Let the total amount shared be x

7/22= 20/x

cross multiply

7x= 22*20

7x= 440

divide both sides by 7

x= 440/7

x= 62.85
