Whole formula 2*pi*radius^2 + 2*pi*radius*height:
157+942= 1099
SA= 1099
i) x²
ii) (x-10)²
b) (x-10)² = x² - 20x + 100
c) (30-10)² = 400 cm²
d) (x-10)² = 144 => x-10 = √144 => x = 12 + 10 = 22 cm
Answer:
23
Step-by-step explanation:
Using the best fit equation y = 1.5x - 1
with x = 16 ( number of years since 2000 ), then
y = (1.5 × 16) - 1 = 24 - 1 = 23
Answer:
5x+6y
Step-by-step explanation:
