<span>So we want to know how much clay did Joseph add after he built the cone. So the formula for the volume of the cone is V=(1/3)*pi*r^2*h where r is the radius and h is height. We know h1=12cm and r1=6cm, r2=6cm and h2=18 cm. So to get the amount of added clay Va we simply subtract the volume of the clay of the first cone V1 from the volume of the second cone V2: Vd=V2-V1=(1/3)*pi*(r1^2)*h1 - (1/3)+pi*(r2^2)*h2. Va=678.24 cm^3-452.39 cm^3= 266.08 cm^3.</span>
Answer:
2x + 3.
Step-by-step explanation:
x + x + 3
= 2x + 3.
Answer: 14/285
Step-by-step explanation:
B = 10
G = 8
T = 18
So its a 8/20 that 1 is a girl but then 2nd its 7/19 and 3rd 6/18 so
8/20 * 7/19 * 6/18 = 14/285
The answer is 10 1/2.
First you need to convert 4/5 and 7/10 so the denominator is the same. 4/5=8/10, 7/10 stays the same.
Now we add= 6 8/10 +3 7/10 =9 15/10.
9 15/10=10 5/10=10 1/2.
Hope this helps and hope you have a great day and please make brainiest
