Here are the operations found:
4y = 4 · y → multiplication of 4 by y
7/d = 7 ÷ d → 7 by d division
t + 8 → sum of t with 8
3 + t → sum of 3 with t
Answer:
414.12
Step-by-step explanation:
78.5cm^2
Circumference equation = 2πr with radius r
10π = 2πr so r = 10π/2π = 5
Area of circle = πr^2
π * 5^2 = π * 25 = 25π = 78.53981... = 78.5 cm^2
9 hour and 30 minutes is the answer to 2
