Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3

Answer:Height to width is 3:4
Width to height is 4:3
Step-by-step explanation:
A TV screen is 15 inches high and 20 inches wide.
Height of TV screen is 15 inches
Width of TV screen is 20 inches
To find ratio of Height to width
we replace the numbers in the ratio Height : width
15: 20
Divide both numbers by 5, so ratio becomes
3: 4
Height to width is 3:4
To find ratio of Width to height
we replace the numbers in the ratio Width : height
20:15
Divide both numbers by 5, so ratio becomes
4:3
Width to height is 4:3
