Answer
Check Explanation
Step-by-step explanation
The volume of cone is given as
Volume of a cone = ⅓ (πr²h)
where
r = radius of the cone
h = height of the cone
also note that radius of a cone = ½ (Diameter of the cone)
1) Dylan's cone
Radius = 4.5 inches
Height = 6 inches
Volume = ⅓ (πr²h)
= ⅓ (π × 4.5² × 6)
= ⅓ (381.7035)
= 127.23 in³
2) Shane's cone
Radius = ½ (Diameter of the cone)
Diameter of the cone = 4.5 inches
Radius = ½ (4.5) = 2.25 inches
Height = 6 inches
Volume = ⅓ (πr²h)
= ⅓ (π × 2.25² × 6)
= ⅓ (95.426)
= 31.81 in³
3) Jake's cone
Radius = ½ (Diameter of the cone)
Diameter of the cone = 6 inches
Radius = ½ (6) = 3 inches
Height = 4.5 inches
Volume = ⅓ (πr²h)
= ⅓ (π × 3² × 4.5)
= ⅓ (127.2345)
= 42.41 in³
4) Grace's cone
Radius = 6 inches
Height = 4.5 inches
Volume = ⅓ (πr²h)
= ⅓ (π × 6² × 4.5)
= ⅓ (508.938)
= 169.65 in³
Hope this Helps!!!
