8hrs = 480mins
6hrs = 360 mins
472/480 = 0.983...
0.983... x 360 = 354
D) 354
Volume of the cylinder = πr²h = π(1)² (21) = 21π cm³
Volume of the cone = 1/3 π r² h
21π = 1/3 π (r)² (7)
r³ = 21π ÷ (7/3 π)
r² = 9
r = 3
Answer : Radius = 3
Answer:
yes
Step-by-step explanation:
Answer:
E looks like it is most congruent
Step-by-step explanation:
You will find the side by 28 ÷ 4 = 7 ft because a square has 4 equal sides.
Then we will do side × side to find the area of a square, so 7 × 7 = 49 ft²
So the answer is 49ft²
