r = 5 yd.

Area =_____ square yards

Circumference =_____ yards

Answer 1

78.5

31.4

Explanation:

Area is πr² so (5²)π = 78.5

Circumference is 2πr so 2(10)π /2= 31.4

Answer 2

Area = 78.5 sq yds

Circumference = 62.8 yds

Explanation:

Area is πr² so (5²)π --> 78.5

Circumference is 2πr so 2(10)π --> 62.8
