Answer:
2500pi^2 units
Step-by-step explanation:
Circumference = pi * diameter
Circumference = pi * 100
Radius = diameter/2
Radius = 50
Area = pi * radius^2
Area = pi * 50^2
Area = pi * 2500
Area = 2500pi^2 units
Here is the correct answer, and explanation for how to get the answer, and a way to remember how to use them for next time :)
Answer:
p= a +2b
Step-by-step explanation:
Making p the subject of the equation means that we need to arrive at the final answer of p= ____.
a= p -2b
a +2b= p <em>(</em><em>+</em><em>2b</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
p= a +2b
Answer:
Step-by-step explanation:
<em>In a regular pentagon, all the angles and sides are equal. So, to find an angle, divide 540 by 5.</em>
Sum of all angles of regular pentagon = 540
measurement of one angle = 540 ÷ 5
= 108°
∠N = 108°
