Answer:
Step-by-step explanation:
V, r, h are the volume, radius, and height, respectively.
V = πr²h = 9πr²
The only error in your previous answers was that you forgot the π.
if r = 1, V = 9π1² = 9π ≅ 28 in³
if r = 2, V = 9π2² = 36π ≅ 113 in³
if r = 3, V = 9π3² = 81π ≅ 254 in³
Answer:
72
Step-by-step explanation:
We need to multiply all of them because there are 3 choices for jackets, 6 for scarves and so on.
all i can really say is it is a y angle
Saw A = 150 planks/30 seconds = 5 planks per second
Saw B = 130 planks/ 13 seconds = 10 planks per seconds
5 + 10 = 15 planks per second total
225 planks / 15 planks per second = 15 seconds
Answer: 15 seconds
