Answer:
<u>1. 40.97 2. 52.93 3. 32.00 4. 26.00 </u>
Step-by-step explanation:
remember that area =1/2 * b * h so to find base, you can make it the subject of formula i.e
b =area *h/2
or in the caseof h you can do
h= area * b/2
Answer:
Step-by-step explanation:
1km = 1000m
5a. 5.768km = 5768m = 57.7m
5b. 9.039km = 9039m = 90.4m
5c. 8.48km = 8480m = 84.8m
5d. 17.685km = 17685m = 17.7m
5e. 17.658km = 17658m = 17.7m
To round to the nearest 100m just divide by 100 and then round it off. like 57.68=57.7m because 8 is more than 5 so 6 becomes 7 to one decimal.
Rule is applied for all the other questions too.
Answer:
C) 
Step-by-step explanation:
The formula for area is
A=pi * radius ^2
If the diameter is 40, the radius is 20
Therefore
