Formula for the circumference of a circle: C = pi x diameter
We are given the radius here, but we need the diameter. The diameter of a circle is equal to two times the radius.
diameter = 40 x 2 = 80 in
C = pi x 80
C = 80pi = 251.3 in
Hope this helps!! :)
Answer:she can make approximately 5 invitation cards
Step-by-step explanation:
Jada is making circular birthday invitations for her friends the diameter of he circle is 12 cm
Diameter of circle,D = 12
Circumference of the circle being made which means the distance round the circle =πD= 3.142×12=37.704 cm
she bought 180 cm of ribbon to glue around the edges of the invitation.
The number of circular birthday invitation that can made is 180/37.704
= 4.77. It cannot be a fraction because the card is a whole card
This is approximately 5 invitation cards
No; 4^2 + 6^2 =/ 7^2
4^2 + 6^2 = 52
Hello :
x²-6x+5 =(x-5)(x-1)
x²+6x+5 = (x+1)(x+5)
5x+5 = 5(x+1)
(x-5)(x-1)×5(x+1) /(x+1)(x+5)×(x+5)
= (x-5)(x-1)×5 /(x+5)×(x+5)
=5(x-5)(x-1) /(x+5)×(x+5)
