The lateral surface area l of a cone varies jointly as the base radius r and the slant height l, and l =63π m2 when r = 3.5 m and l = 18 m. find r to the nearest tenth when l = 8πm2 and l = 5 m.

Hi there

Use the formula of the present value of annuity ordinary
The formula is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value?
PMT payment per month 800
R interest rate 0.0475
K compounded monthly 12
N time 30 years

Pv=800×((1−(1+0.0475÷12)^(
−12×30))÷(0.0475÷12))
=153,360.32answer

Hope it helps
