Answer:
- area: 36π ≈ 113.1 . . . . square units
- circumference: 12π ≈ 37.7 . . . . units
Step-by-step explanation:
The area formula is ...
A = πr^2
A = π(6^2) = 36π ≈ 113.1 . . . . square units
__
The circumference formula is ...
C = πd
C = π(12) = 12π ≈ 37.7 . . . . units
Answer:
60 degrees
Step-by-step explanation:
11: 180 = x + x + x
180 = 3x
x = 60 degrees
Since you're painting the sides of the cube, you will need the equation for the surface area of a cube, which is
, where SA = surface area and s = length of an edge of the cube.
You're told that the edge length, s = 2cm. Plug this into the equation for surface area:
The surface area that will be painted is <span>
24 cm².</span>
Answer:
541.8 cm³
Step-by-step explanation:
Volume of a prism is the height times the area of the base.
V = hA
Area of a rectangle is width times length, so:
V = hwl
Given h = 8.8 cm, w = 4.7 cm, and l = 13.1 cm:
V = (8.8 cm) (4.7 cm) (13.1 cm)
V = 541.8 cm³
