Answer:
C. 4
Step-by-step explanation:
A pancake is circular in shape
Hence, the area of a circle = πr²
HenceThe corner shop charges
a) $12 for a 3-inch personal pancake.
For personal pancake
r = 3 inches
πr² = π × 3²
= 28.274333882 square inches
= 28.3 square inches
b) The largest pancake is a 6-inch pancake that costs $20.
For Largest pancakes
r = 6 inches
πr² = π × 6²
= 113.09733553 square inches
Approximately = 113.1 square inches
How many times larger is the area of the largest pancake than the personal pancake?
This is calculated as :
Largest pancake/Personal pancake
= 113.1/28.3
3.9964664311 inches
Approximately = 4
Option C is the correct option

Answer:
0 handshakes
Step-by-step explanation:
There are 8 women of different heights.
Let the eight women be A, B, C, D, E, F, G and H
Assume A is taller than B and A decides to shake hands with B, B will refuse because A is taller. If this happens across the eight women then there will be 0 hand shakes.
If this assumption is taken out, we have 7+6+5+4+3+2+1 = 28
Answer:
2140
Step-by-step explanation:
Year one. 1300
year 2. 120. 1420
year 3. 120. 1540
year 4. 120. 1660
year 5. 120. 1780
year 6. 120. 1900
year 7. 120. 2020
year 8. 120. 2140
or
7 x 120=840
1300 + 840 = 2140
