Answer:
The circumference of clock is, 53.38 cm
Step-by-step explanation:
Circumference(C) of the circle is given by:
....[1]
where, r is the radius of the circle.
As per the statement:
the radius of a clock face is 8.5 centimeters
⇒r = 8.5 cm
Use
Substitute the given values in [1] we have;
Simplify:
C = 53.38 cm
Therefore, the circumference of clock is, 53.38 cm
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
