1. I don’t know exactly what you need but 4 divided by 7 is about 0.57 feet or 6.86 inches
2. If you are allowed excess, then you will have 7 pieces each at 0.5 feet with half a foot left extra
Volume of a cone = 1/3πr²h
r = 5.7/2 = 2.85
h = 12
Volume of original design =1/3π(2.85)²(12)
= 32.49π
= 102.07.....
Linear scale factor = 1.5 = 3/2
Volumetric scale factor = (3/2)³ = 27/8
Volume of revised design = 102.07..... × 27/8
= 344.487..... ⇒ 344.5 in³
Answer:
121
Step-by-step explanation:
First do the parenthesis. Now your equation is (11)^2 Next do exponents. Your equation now is 121.
Hope this helped and have a great day!
