Answer:
Step-by-step explanation:
Pyramid height should be 14
Base area should be 14*14(196)
So, Base area is 196
1. Multiply the Base area by the height of the pyramid:
196*14=2744
2. Divide the number above by 3:
2744/3=914.7
Answer:
1) 113.0 m^2
2) 12.6 ft^2
3) 50.2 in^2
4) 153.9 m^2
5) 254.3 yd^2
Step-by-step explanation:
pi (3.14) times radius squared
1) 3.14 times 6^2 (36)
113.04
2) diameter is given, divide by 2 to find radius
3.14 times 4^2
12.56

Answer:
Step-by-step explanation:
Let h be the number of hats Elliott makes and s be the number of scarves she makes.
Each hat uses 0.2 kilograms of yarn and each scarf uses 0.1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats. This is expressed as
h = 2s
The total number of hats and scarves that she wants to make is 20. This is expressed as
h + s = 20
Therefore, the system of equations that represents this situation are
h = 2s
h + s = 20
Answer: 76 degrees
