The diameter of a circle is 3 cm. Find its area to the nearest tenth. A=A=
\text{ cm}^{2} cm
2

Step-by-step explanation:

diameter = 3 cm

radius = 3/2 = 1.5 cm

Area of circle = πr²

                      = 3.14 * 1.5 *1.5

                       = 7.065

                      = 7.1 square cm

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
