diameter (d)= 2r=2*4=8ft
Step-by-step explanation:
circumference =2πr
=2 *4*22/7
=25.14 ft
also
Area=πr^2
=4^2 *22/7
50 .28 sq ft
Answer:
Diameter: 8ft
circumference: 25.12
area: 50.24 square feet
radius is 4ft
Diameter is 8ft
circumference 2×pi×radius
2×3.14×4
25.12
area (pi)radius^2
3.14×(4)^2
3.14×(16)
50.24
50 square feet
