For the answer to the question above, \
Let
D = Dominic weight
R = Ralph weight
P = Peter weight

We have three unknowns so we should set up three equations. We do as follows:

D = 0.5R
P = 3D
D+R+P = 720

Solving simultaneously we obtain,

D = 120
R = 240
P = 360

<span>So the answer is 120 is the weight of Dominic</span>

Answer:

circumference=>2πr

circumference= 119.32 cm

π = 3.14

r =?

119.32 = 2 × 3.14 × r

r = 119.32/6.28

r = 19 cm

so area = πr²

area = 3.14 × (19)²

area = 3.14 × 361

area = 1,133.54 cm²
