Answer:
(1/3)πr2h.
Step-by-step explanation:
Volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
Base surface area of a cone (a circle):
B = πr2
Total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Answer:
P(1 and 2 are green) = 3/25
Step-by-step explanation:
We need to know the total number of marbles
6 Blue + 10 red + 9 green = 25 marbles
P ( 1st marble is green) = green/ total
= 9/25
Since we don't put it back, there are
6 Blue + 10 red + 8 green = 24 marbles
P ( 2st marble is green) = green/ total
= 8/24 = 1/3
P(1 and 2 are green) = P(1st green) * P(2nd green)
= 9/25 * 1/3
= 3/25
Each long piece is composed of 10 unit blocks (smallest squares).
The three long pieces means that they make up 3*10 = 30 units so far. Add on the 5 extra units and we have 30+5 = 35 units total
If we have 35 squares, then we can group them up into groups of 5. Doing so will leave you with 7 groups.
