To multiply whole numbers and fractions, multiply the numerator by the whole number. Example: 1/3×4= 4/3=1 1/3
Answer:
A = 3W² + W + 1/8πW²
Step-by-step explanation:
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
A = 3W² + W + 1/8πW²
The answer is b. 9pi because 3^2xpi=9pi.
Decimals because money is expressed in decimals and we handle with money every day.
