Answer:
Radius = 11.85yd
Step-by-step explanation:
Volume of a Cone formula: V = πr²(h/3)
We know that;
V = Volume
r = radius
π = pi (this is a sign located on your calculator)
h = height
We are given that;
V = 4,410
r = unknown
h = 30
Let's substitute the values in:
=> V = πr²(h/3)
=> 4,410 = πr²(30/3)
=> 4,410 = πr²(10)
=> 4,410 / 10 = πr²
=> 441 = πr²
=> 441 / π = r²
=> 140.37 = r²
=> = r
=> 11.85 = r
Therefore, <u>the radius of the cone = 11.85yd</u>
Hope this helps!
Answer:
The value of x and y is ,
x = and y = 2
Step-by-step explanation:
The given two linear equation can be written as ,
y + 9x = -13 ....1 and
y - 3x = 7 .....2
Put the value of y from eq 1 into eq 2
i.e (-13 -9x) - 3x = 7
or, -12x = 7 +13
Or, -12x = 20
i.e X =
Now put t his value of x in any above two linear equation
Let put this value on eq 2 to get value of y
so its can be writen as.
y = 3x + 7
or, y = 3() + 7
or, y = -5 +7
i.e Y = 2
Hence the value of x and y is , x = and y = 2 Answer
