Answer:
it is roughly 0.18cm
Step-by-step explanation:
we have 2 measurements here
actual measurement = 8.6cm(bird's height), ? (beak)
photo measurement = 52.4(birds height), 1.1 (beak)
if 52.4 = 8.6
1.1 = <u>1.1 x 8.6</u>
52.4
= it is roughly 0.18cm

Answer:
496.6
Step-by-step explanation:
circumference of circle=8pie^2
2*pie*r=8*pie^2
2*r=8*pie
2r=8*22/7
r=176/7÷2
r=12.57
Area of circle=pie*r^2
=22/7*12.57^2
=22/7*158
=496.6
The perimeter of the entire figure is 62.8 cm.
Given, that the diameter of the inner semicircles is 9 cm and the width between the outer and inner semicircles is 2 cm.
The radius of the inner semicircle =4.5 cm and the radius of outer semicircle =5.5 cm (∵Diameter=9+2=11 cm)
We need to find the perimeter of the entire figure.
<h3>What is the perimeter?</h3>
A perimeter is a closed path that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
We know that, the circumference of a semicircle=πr and the circumference of two semicircles=2πr
Thus, the circumference of inner semicircles=2×3.14×4.5=28.26 cm
The circumference of outer semicircles=2×3.14×5.5=34.54 cm
The perimeter of the entire figure=28.26+34.54=62.8 cm
Therefore, the perimeter of the entire figure is 62.8 cm.
