Hello there,
Okay well first we right down what we already know:
- volume of 2,355 cubic inches
- the height is 10 inches
Now we write down the equation for the volume of a cone: V = πr²
- lets plug in what we know into the equation
2,355 = πr²
- now we simplify to solve for r
2,355 / 10/3 = 706.5 = πr²
706.5/π = r²= 224.89
- now since its r² we take the square root of 224.89
r = 15 inches
- for diameter we multiply 15 by 2
diameter = 30 inches
Hope I helped,
Amna
Answer:
f(3) =19
Step-by-step explanation:
f(x)=2x^2+1
Let x = 3
f(3) = 2(3)^2 +1
Exponents first
=2(9) +1
Then multiply
=18+1
=19

Answer:
3/6, 2/6.
Step-by-step explanation:
The lowest common denominator of 2 and 3 is 6.
1/2 = 3/6 and 1/3 = 2/6
So this pair of fractions is 3/6, 2/6.
Answer:
EcD= 52 DCB=128
Step-by-step explanation:
First, let's find out what x equals and what (x+11) equals
And therefore...
Now angle ecd is a vertical angle we just found.
So angle ECD= 52 degrees
And agles ECD and DCD and supplimntary
