Answer:
8cm^2
Step-by-step explanation:
4*2=8
Answer: the exact perimeter of the figure is 53.68 cm
Step-by-step explanation:
The angle formed by the shaded sector is
360 - 90 = 270 degrees
We would determine the length of the arc formed by the shaded portion by applying the formula for length of arc which is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 8 cm
θ = 270 degrees
Length of arc = 270/360 × 2 × 3.14 × 8
= 37.68 cm
Perimeter of the figure is
Length of arc + radius + radius
It becomes
37.68 + 8 + 8 = 53.68 cm
A hexagonal prism should work! The two bases are hexagons, and there are 6 lateral faces that are rectangles. When you count the edges, there are 18... here's an image of one (just in case)
