Answer:
104 yd^2.
Step-by-step explanation:
Area of the 2 circles = 2 * π r^2
= 2 * π * 4^2
= 32 π yd^2.
Area of the side of the cylinder = 2 π r h
= 2 π * 4 * 9
= 72 π yd^2.
Total surface area = 32 + 72
= 104 yd^2.
X = nr. hrs working for a farmer;
y = nr. hrs. babysitting;
x + y <= 25;
10x + 5y >= 150
a) Solve the system => one of the solution is x =5; y = 20(babysitting)
b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.
The parts (a) to (c) can be completed using the equtaion y ⇔ Δ ∈ ∞, ㏒Δ ∀ x∈√a, a∈R.
Answer:
22.5 cm
Step-by-step explanation:
P = 2( L + W)
P = 2( 7.5 + 3.75)
P = 2( 11.25)
P = 22.5 cm
The answer is 44/7 hope this helps
