Answer:
Perimeter of the sector = (36 + 8π) cm.
Step-by-step explanation:
Formula to find the of an arc of the circle is,
Length of the arc =
Here, θ = central angle formed by the arc
r = radius of the circle
Therefore, length of the arc given in the picture =
= 8π cm
Perimeter of the sector = Sum of all sides of the sector
= Length of radius + length of the arc + length of radius
= 18 + 8π + 18
= (36 + 8π) cm
Perimeter of the sector is (36 + 8π) cm.
Answer:
Step-by-step explanation:
We can divide it into two parts:
First, we can fin the volume of the parallelepiped:
h1 = 16 cm
w1 = 2 cm
d1 = 3 cm
Now, the volume of the second parallelepiped is:
h2 = (8-2) cm = 6 cm
w2 = 2 cm
d2 = 3 cm
Finally, the total volume will be the addition of these two volumes.
I hope it helps you!
