It’s definitely is A,D, and C
Area of a semicircle is 1/2* πr^2
Area of a square is s^2
Square’s area: 4mm^2
The radius is 3mm
Plug into the equation
1/2* π(3^2)
1/2* π(9)
We can use 3.14 as an estimate of pi
1/2*28.26
14.13mm^2
Now just add them both
Total area 18.13mm^2
Speed = 90km/hr
Time = 1min = 1/60 hr
Speed = Distance / Time
Distance = Speed * Time
D = (90 km/hr) * (1/60 hr)
D = 1.5 km (ANSWER)
Answer:
80%
Step-by-step explanation: Because if 20% of 250 equal 50 then 200 is 80% because adding 4 50 is 200.
