Answer:
2.43 (units)
Step-by-step explanation:
Circumference of a circle is defined by C=2pi*r
Solving that equation for r --> 5.5 = 2* 3.14 * r
r=0.88 unit
Area of a circle = A= pi * r^2
Solve this equation by plugging in the r we just found. A = 3.14 * (0.88^2)
Answer: 2.43 units
Answer:
Number of dimes Sandy has = (20 - x)
Step-by-step explanation:
Let the number of nickels Sandy has = N
And the number of dimes she has = D
Total number of coins she has = 20
N + D = 20 ------(1)
If she has the number of nickels = x
Therefore, expression that represents the number of dimes she has will be
x + D = 20
D = (20 - x)
Number of dimes Sandy has = (20 - x)
Yes because next year she will be 47 inches tall then in two years she will be 49 inches tall.
