Volume of cone: pi * r^2 * h/3
Given volume, height
942in^3 = 3.14 * r^2 * 9/3
942in^2 = r^2 * 9.42
Divide by 9.42
r^2 = 100, r = -10, 10
Cannot be negative so...
Solution: radius is 10 in.
Answer:
17
Step-by-step explanation:
1+7p-40=80
-39+7p=80 Move constant to the right
7p=80+39 add the numbers
7p=119 divide both sides by 7
Answer:
B) 
Step-by-step explanation:
First simplify the radical on the right.
is equal to
, because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know
is just equal to 25, which means the simplified version of
is
.
Then we can use this new representation to finish solving.
, so the answer would be B
Answer:
14 cm
Step-by-step explanation:
The applicable formula is ...
s = rθ
s = (7 cm)(2) = 14 cm
Answer= .2 probability
Explanation: Since there is a total of 10 marbles, and 2 are red, you would divide the red marbles (2) out of the total marbles (10) which would get u .2. Since it’s asking for probability, we would keep .2 a decimal.
