To find how much money they shared first find the total parts
Which is
5 + 7 + 8 = 20
Deila's share is
5 /20 × £1600

Freya's share is
8/20 × £1600
= 2/5 × £1600 = £640
Hope this helps you
Answer: A=1/4 πd^2
Plug diameter into D solve for A
Step-by-step explanation:
Formula for area of a circle. Area = 1/4 pie•diameter squared
Answer:
see explanation
Step-by-step explanation:
Using the given formula for area : A = 
bh
(a) given b = 8 and h = 5, then
A = × 8 × 5 = × 40 = 20 units²
(b) given A = 18 and b = 4, then
18 = × 4 × h = 2h ( divide both sides by 2 )
h = 9 units
(c) given A = 14 and h = 7, then
14 = × 7 × b = 3.5b ( divide both sides by 3.5 )
b = 4 units
