Question

Pls help !!

Answer 1

Answer:

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

Answer 2

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
