Answer:
Sphere Volume = (4/3) * PI * radius^3
radius = cube root (Sphere Volume) / (4/3)*PI
radius = cube root (5,600) / (4/3)*PI
radius = 11.016 cm
radius = 11 cm (rounded)
Answer is B
Step-by-step explanation:
Answer:
1 / 27 cm^3
Step-by-step explanation:
Given,
side = 1 / 3 cm
To find : Volume ( cube ) = ?
Formula : -
Volume ( cube ) = ( side )^3
Volume ( cube )
= ( 1 / 3 )^3
= 1^3 / 3^3
= 1 / 27
= 1 / 27 cm^3
Answer:
The total cost is <em>28.26.</em>
Step-by-step explanation:
The radius of the birdbath is <em>1.25 feet.</em>
The cost per foot is <em>3.6</em> .
<em>The formula for perimeter of circle is given by,</em>
<em>= 2πR , where R is the radius of circle.</em>
Inserting the above value of radius in the equation above,
circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Thus the total cost is,
= (7.85)(3.6) = 28.26
