Answer:
84 circular tiles are needed to make pattern number 20
4(20+1)
Step-by-step explanation:The number of circular tiles is 1 more than the pattern number on each side of the square.
circular tiles = 4(n +1)
You have to write an equation that can help you solve the problem like x + 4 = 26 then solve for x.
Answer:
its right!
Step-by-step explanation:
25 trucks in 5 h
25/5 = 5 trucks an hour
35/5= 7 cm so we have found ''d'' of a circle. R=1/2 d =3.5 cm
The triangle base contains of three full circles 3*7=21 cm + 2 half circles which make a full one =7
AB= 7+21=28 CM
To find the height CH (Name the triangle ABC and the height CH) we do the same calculation. 2 half circles= 1 full + 1 full = 2 full = 2*7=14 cm.
The area is : AB*CH/2 = 28*14/2= 196 cm 2
I hope you understood because it's not the way I am used to explain Math exercises, because of my native Albanian language :)
