Answer: 113.1 cm^2
Step-by-step explanation: The formula to find the area of a circle is 3.14r^2. R stands for radius which is 6 in this case so just plug that in for R. 3.14(6)^2=113.1
Answer:
132
Step-by-step explanation:
Answer:
Height = 5.6cm
Step-by-step explanation:
Area = 1/2bh
b = 10cm, area = 28cm^2
:- 28 = 1/2 × (10)h
28 = 5h
h = 28/5
h = 5.6cm
Answer: D. n + q = 20
5n + 25q = 300
Step-by-step explanation:
Let n represent the number of nickels that you have.
Let q represent the number of quarters that you have.
Suppose you have 20 coins. It means that
n + q = 20
The total value of the coins is $3. The value of a quarter is $0.25 and the value if a nickel is $0.05. Therefore, the equation would be
0.05n + 0.25q = 3
Multiplying both sides of the equation by 100, it becomes
5n + 25q = 300
The correct option is
D. n + q = 20
5n + 25q = 300
Answer: 2 = 28 (72+28 = 90)
Step-by-step explanation:
no picture attached, if it is a right angle angle 2 = 28 (72+28 = 90)
