HEY THERE !!

As we know that the area of a circle (A)= πr^2

But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}

Here diameter is 10.5 inches.

A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}

So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.

HOPE IT HELPED YOU.

I think it's suppose to go

6% is .06 divided by 12 which is .005 times the number of months so in this case 9 so 5,000 times .005 times 9 which is 225 so 5,000 plus an interest of 225 adds up to 5,225
