Answer:
The volume is 140 cm3. See the explanation below, please
Step-by-step explanation:
We use the formula:
Volume (V) = 4/3 pi r ^3
V= 4/3x 3, 14x (6,44/2)^3 = 139,8 cm3= 140 cm3
Answer:
Step-by-step explanation:
Circumference = 2pi r
440 = 2 *22\7 *r
70 = r
Area= pi r^2
Area= 22\7 *70*70
Area =15400
Answer:
