Answer:
Task 2
1.) 254.47cm²
2.) 113.1in²
3.) 50.27ft²
4.) 706.5cm²
5.) 12.57m²
6.) 1808.64m²
Task 3
1.) 3216.99cm²
2.) 1809.56m²
3.) 0.38m²
4.) 973.14cm²
5.) 795.77m²
Step-by-step explanation:
Task 2
1.) A=πr2=π·92≈254.469cm²
2.) A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·122≈113.09734in²
3.) A=πr2=π·42≈50.26548ft²
5.) A=πr2=π·22≈12.56637m²
Task 3
1.) A=πr2=π·322≈3216.99088cm²
2.) A=1 4πd2=1 4·π·482≈1809.55737m²
4.) A=1 4πd2=1 4·π·35.22≈973.13974cm²
5.) A=C2
4π=1002
4·π≈795.77472m²
Hope it helps kahit wla solutions yung iba.
