Answer:
3.
A) 43.96 cm (Circumference)
B) 153.86 square cm (Area)
4.
A) 62.8 ft (Circumference)
B) 314 square ft (Area)
Step-by-step explanation:
3. Radius 7 cm
7*2=14 (Find the diameter)
14*3.14= 43.96 cm (Circumference)
7*7=49 (Find the square of radius)
49*3.14 = 153.86 square cm (Area)
4. Diameter: 20 ft
20*3.14 = 62.8 ft (Circumference)
20/2=10
10*10=100
100*3.14= 314 square ft (Area)
Answer:
58.995 round to the nearest whole number is 59 miles per hour
Step-by-step explanation:
1 kilometer/hr = 0.62 miles per hour
Therefore 100 km/hr = 100 × 0.621
= 62 miles per hour
95 km/hr = 95 × 0.621
= 58.995 miles per hour
58.995 round to the nearest whole number is 59 miles per hour

Answer: The correct order of the options is 4, 3, 2, 1 and 5.
Explanation:
The steps for analyzing mathematical models are,
To analyzing a mathematical model first we have to defined the problem and identify parameters.
The second step is, defined the data needed. it means determine that which type of data is required according to the problem and parameters and neglect the relevant data.
The third step is collect or gather needed data. To solve the defined problem we need the related data.
The fourth step is arrange or analyse the data according to the requirements.
THe fifth step is after analysing the data draw a reasonable conclusion.
Therefore, the correct order of the options is 4, 3, 2, 1 and 5.
Of two angles and the included side of one triangle are congruent to the corresponding to the corresponding parts of another triangle hen the triangles are congruent. I really don't think there is additional information to prove if the triangles are congruent by using ASA.
Hopes this helps
