Answer:
2^4·3²·5² = 3600
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
A = πr² ← r is the radius and r =
d ← d is the diameter
Hence
π (
d)² = A, that is
= A ( multiply both sides by 4 )
d²π = 4A ( divide both sides by π )
d² =
( take the square root of both sides )
d = 
80-64=24
24 is 30% of 80 so a decrease of 30%
First of all that is NOT math and second of al that is not english
