<span>area of a circle
area = pi r ^2 
64 = 3.14 x r ^2
divide both sides by 3.14 
20.38 = r^2 
square root of 20.38 
4.51 = r 
diameter is twice the radius 
4.51 + 4.51 = 9.02 </span>

What is the area of a circle with a radius of 1 foot?
Lunna [17]

Answer:

3.14 ft² or 2,917 cm²

Step-by-step explanation:

To do this, we need to know the expression to calculate the area of a circle.

The area of any circle is:

A = πr²

Where:

π: value of pi, which is 3.14

r: radius of the circle, in this case 1 ft

Calculating the area in units of ft:

A = 3.14 * (1)²

A = 3.14 ft²

Now, if you convert the foot to cm we have:

1 * 30.48 = 30.48 cm

Solvinf for A:

A = 3.14 * (30.48)²

A = 2,917.15 cm²

Gnesinka [82]

Answer:

C

Step-by-step explanation:

If x is the average (arithmetic mean) of m and 9, y is the average of 2m and 15, and z is the average of 3m and 18,

x=(m+9)/2

y=(2m+15)/2

z=(3m+18)/2

the average of x, y, and z

=(x+y+z)/3

=(m+9+2m+15+3m+18)/3

=(6m+42)/3

=2m+14

ans is C
