Answer:
<u>1.28 in³</u>
Step-by-step explanation:
<u>Volume of Amy's cone</u>
- Cone = 1/3πr²h
- Cone = 1/3 x 3.14 x 1² x 6
- Cone = 2 x 3.14 = 6.28 in³
<u>Volume of Don's bowl</u>
<u>Difference</u>
- Amy's cone - Don's bowl
- 6.28 - 5
- <u>1.28 in³</u>
John would e 24 and mark would be 12
Use the formula for finding axis of symmetry:
-b -25 -25
x = ------ ⇒ --------- = -------- = 2.6
2a 2(-4.9) -9.8
First step: Find how wide the bulletin board is
15 ft² ÷ 3 ft = 5 ft
Step the second: Use the perimeter formula P = 2l + 2w
P = 2(5) + 2(3)
<u>P = 16 ft</u>
