Answer:
21cm, 24cm and 27cm
Step-by-step explanation:
7+8+9=24
72/24 = 3
7X3 =21
8x3 = 24
9x3 = 27
10% of 55 is 5.5
You could divide 55 by 10 to get 5.5 or multiply 55 by the decimal representation of 10% which is .1
.1 x 55 = 5.5
55 / 10 = 5.5
Answer:
Step-by-step explanation:
At least 21....I hope you pass what ever you are doing!
Area=πr^2
find the area then divide by 8
we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
