Answer:
7.7
Step-by-step explanation:
The area of the wall is 4 * 2 = 8.
The radius of each clock is 0.3 / 2 = 0.15.
The area of all 4 circles is 4 * (πr²) = 4 * 3.14 * 0.15² = 0.3.
8 - 0.3 = 7.7
Answer:
6.9
Step-by-step explanation:
Total area of the wall is 4 x 2 = 8
Area for a circle is π x radius^2
Therefore total area of 4 clocks = 4 (π x 0.3^2)
Which is: 1.13...
Now we take away this answer from the area of the wall:
8 - 1.13... = 6.9 (1 d.p)

Answer: 18
Step-by-step explanation:
Answer:
y=15/7x-4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(11-(-4))/(7-0)
m=(11+4)/7
m=15/7
y-y1=m(x-x1)
y-(-4)=15/7(x-0)
y+4=15/7(x)
y+4=15/7x
y=15/7x-4
