Assuming the room is a rectangle...
The area of a rectangle = its length × its width.
The amount of carpet we need to cover our rectangular room = 8.5 ft × 7.5 ft
Use decimal long multiplication or otherwise to get 63.75 ft².
To get the speed of growth of plant we proceed as follows;
rate=(distance)/(time taken)
distance( length) of growth of the plant in 14 days is 3.6 m.
1 day=86400 sec
14 days=86400x14=1,209,600 sec
1 m=1000000 micrometer
3.6 m=3600000 micrometer
thus the rate of growth will be:
3600000/1209600
=2.9762 micrometers per second
Answer:
6ft
Step-by-step explanation:
Answer:
135 ft^3
Step-by-step explanation:
The volume of a cone is 
. The radius is 4 and the height is 8, so these values can be plugged in:
This is about 134.041286553 which rounds to 135 ft^3.
7x9 = 63
63x2 = 126
126 is the surface area
