Answer:
3b
Step-by-step explanation:
if each brick is 3 inches tall, and there are b bricks, each b is 3, therefore 3b
So using the formula for the volume of a cone:
r^2pi x h/3
The height is always 4 times the radius, so:
h=4r
Now putting the values into the original formula:
r^2pi x 4r/3
Now to see how much the radius increases per second:
r^2pi x 4r/3=300pi
r^2 x 4r/3=300
r^2 x 4r=900
r^2 x r=225
r^3=225
The radius increases by the cubic square root of 225 cm per second.
f(s)= 225^1/3 cm
Answer:
36π mi
Step-by-step explanation:
Area of a circle = πr²
Diameter = 12 mi. Therefore, radius=12/2 = 6 mi
πr²
π x (6)²
π x 36
Hence, the answer is 36π mi
Answer:
6/11, 15/21, 9, 27/37, 31/54
Step-by-step explanation:
Absolute value is when you determine the distance between a value and zero . Since you will always have a positive distance, your absolute values are positive as well.
