Area of a circle formula:

A = \pi r^{2}

You're given that A = 615.75, so:

615.75 = \pi r^{2}

Solve for r:

r =  \sqrt{(615.75/ \pi )}

r = 14 cm

Diameter is equal to twice the radius, so doubling 14 gives you
d = 28cm

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
