What is the circumference of this circle? Use 3.14 for π.
12 cm.
Sorry, I cannot determine the circumference of a circle without knowing its radius or diameter. Please provide more information.
Diameter = 12
Great! The formula to find the circumference of a circle is C = πd, where d is the diameter.
Using that formula and substituting the given value, we get:
C = πd
C = 3.14 x 12
C = 37.68 cm
Therefore, the circumference of a circle with diameter 12 cm is 37.68 cm.
What is the volume of the rectangular prism if all side are 3 units
The volume of a rectangular prism is given by the formula V = lwh, where l, w, and h are the length, width, and height of the prism, respectively.
Since all sides of the prism are given as 3 units, we have:
l = 3 units
w = 3 units
h = 3 units
Substituting these values into the formula, we get:
V = lwh
V = 3 x 3 x 3
V = 27 cubic units
Therefore, the volume of the rectangular prism with all sides equal to 3 units is 27 cubic units.
