If the diameter of a circular wall clock is 30 cm, what is the area of rhe clock?​

Here area would be 225π cm² or roughly 706.85 sq

. :The area of a circle is πr² , or pi times the radius squared.

Since diameter is 30cm

The raidus is simply half of the diameter or 15cm

:-radius is twice of diameter so if the diameter is 30 cm then the radius is 15cm.

Step-by-step explanation:

Hope itz helps uh♡

Step-by-step explanation:

radius=diameter/2

=30/2

=15 cm

area of a clock=πr^2

=3.14*(15)^2

=3.14*225

=706.5 cm^2

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
