The surface area of the hat can be found using the formula A = 4
r.
Since the radius is half of the diameter you would divide the diameter by 2 to get a radius of 8. You then substitute r for 6 in the formula and get the surface area.
A = 4
6
A = 804.25
Answer:
Step-by-step explanation:
1) r = 5mm; d = 10 mm
2) r = 6 cm; d = 12 cm
3) r = 9 m; d = 18 m
4) r = 8 km; d = 16 km
5) r = 11 m; d = 22 m
6) r = 15 mm; d = 30 mm
7) r = 13 km; d = 26 km
8) r = 7 cm; 14 cm
Answer:
Infinity
Step-by-step explanation:
4,6 and 4,10
10 - 6=4
4 - 4=0
4 divided by 0 = Infinity
