Answer:
37.68 cm.
Step-by-step explanation:
In the given figure, the radius of the circle is 6 cm. As we know the formula for Circumference of Circle is 2πr,
= 2×22/7×6cm
= 37.68 cm
The answer is 520x.
Let x be the price of wallpaper per square feet.
Dimensions of a kitchen are:
width: w = 12 ft
length: l = 14 ft
height: h = 10 ft
If you need to put wallpaper in the room, you will put it only on the walls. There are 4 walls in the kitchen: two walls which dimensions are 12 ft and 10 ft, and two walls which dimensions are 14 ft and 10 ft. Since walls are of rectangular shape, we will use the following formula for the area of walls:
A = 2 * w * h + 2 * l * h
A = 2 * 12 * 10 + 2 * 14 * 10
A = 240 + 280
A = 520 ft²
So, if 1 square foot costs x, 520 square feet will cost 520x
