Answer:
Area is 1384.74
Circumference is 131.88
Step-by-step explanation:
42 ÷ 2 = 21
21 = radius
C=2(pie sign lol)r
2×3.14×21
131.88 ^
A= 3.14r^2
21×21 = 441
3.14×441
1384.74^
nice
Volume = L × W × H
Length L = 17in
Width W = 7in
Height H = 7in
Volume V = 17×7×7
V = 833
Volume = 833 in^3
108
12/4=3
36 x 3 = 108
Speed = Distance / time
Speed = 540 km / 6 hours
Speed = 90 km/hr.
