Pls help !! Find the area and circumference of a circle with a diameter of 10 in. Round to the nearest tenth for both values.

Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 78.5 in

Circumference of circle= 2πr so, 2×5×π= 31.4 in

1.  A = 78.5 in² 2. C = 31.4 in

Step-by-step explanation

1. area of a circle = πr²

2. circumference of a circle = 2πr

where diameter = 10 in.

                radius = 10 / 2 = 5 in

1. area of a circle = π(5)²

                            = 78.5 in²

2. circumference of a circle = 2πr

                                              = 2π(5)

                                             = 31.4 in

The recursive form is very useful when there aren't too many terms in the sequence. For instance, it would be fairly easy to find the 5th term of a sequence recursively, but the closed form might be better for the 100th term. On the other hand, finding the closed form can be very difficult, depending on the sequence. With computers or graphing calculators, the 100th term can be found quickly recursively
