The simple interest i on an investment of p dollars at an interest rate r for t years is given by i=prt. find the time it would take to earn $1400 in interest on an investment of $27,000 at a rate of 4.2%.

we know that

where

I is the amount in interest

P is the investment

r is the interest rate

t is the time in years

Solve for t

we have

substitute

therefore

the answer is

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
