Answer:
264
Step-by-step explanation:
220-22=198
198/3=66 (which is 1/4)
66x4=264
0.3 x 103 = 30.9
0.3 x 1025 = 307.5
3 x 10^5 = 300,000
1) 90
2) 30
3) 150
4) 20
Hope this helped
The difference in area between the top surfaces of the two cakes is 28.26 inches²
<h3>Area of a circle</h3>
where
r = radius
Therefore,
area of top layer = πr²
d = 2r
r = d / 2
r = 8 / 2
r = 4 inches
area of top layer = 3.14 × 4²
area of top layer = 3.14 × 16
area of top layer = 50.24 inches²
area of the bottom layer = πr²
r = 10 / 2 = 5 inches
area of the bottom layer = 3.14 × 5²
area of the bottom layer = 3.14 ×25
area of the bottom layer = 78.5 inches²
Difference in area between the top surfaces of the two cakes can be found as follows:
- 78.5 - 50.24 = 28.26 inches²

Answer:
1 is the answer see attached
Step-by-step explanation:
1 is a function
2 is not a function as it is x+y
3 is a boundary function of how many parameters
4 is not a function as such parameters are too long however many of the decimals divide into each other and appear functional.
