Answer:
4A/ (πa) = b
Step-by-step explanation:
A = πab/4
Multiply each side by 4
4A = 4πab/4
4A = πab
Divide each side by πa
4A/(πa) = πab/ πa
4A/ (πa) = b

Answer:115.4685yd^3
Step-by-step explanation:
Volume of cone=1/3πr2h
V=1/3×3.142×3.5yd×3.5yd×9yd
V=115.4685yd^3
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
(x + 1)² = x² +2*x*1 + 1² = x² + 2x + 1
y = 4(x+1)² - 4
y = 4(x² + 2x + 1) - 4
y = 4*x² + 4*2x + 4*1 -4
y = 4x² + 8x + 4 - 4
y = 4x² + 8x
