What is the area of a circle with a radius of 1 foot?

Answers

Answer 1

Answer:

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

Answer 2

Answer:

Answer:

Pi feet squared

The width of a rectangle is two-thirds of its length, and its area is 216 square meters. What is the length? is it 27 or 12

Answers

Answer:

The length of rectangle =18 m.

Step-by-step explanation:

Suppose of length of rectangle=x

Width of rectangle = $(2)/(3)x$

Area of rectangle = $216 m^2$

We have to find the length of rectangle .

Area of rectangle = $length* breadth$

Substitute the values in the given formula

$216=x* (2)/(3)x$

$216=(2)/(3)x^2$

$2x^2=216* 3$ By multiplication property of equality

$x^2=(216* 3)/(2)$ ( by division property of equality )

$x=√(324)=18$

Substitute the value then we get

Width of rectangle = $(2)/(3)* 18=12 m$

Hence, the length of rectangle =18 m.

Solve the system using elimination.

5x + 8y = –29
7x – 2y = –67

Answers

7x-2y+-67
multiply both sides of the bottom by 4 and add 5x+8y=-29
28x-8y=268

33x=-297
x=-9

5(-9) +8y= -29
-45 +8y =-29
8y= 16
y=2

Answer: Choice C

angle HDG = angle HFE

==========================================================

Explanation:

We have the statement $\triangle DHG \cong \triangle FHE$ given to us. Note that "H" is in the middle for both sequences of three letters. For DHG, start at H and move back one space to get to D. Move back another unit to wrap around to G. So the new sequence is HDG which forms the first angle.

Follow the same pattern but for FHE now. Start at H, move backward one spot to F, then move back again to wrap around to E. We have HFE

This shows angle HDG pairs up with angle HFE. The corresponding angles are congruent due to CPCTC

CPCTC = corresponding parts of congruent triangles are congruent

Notice how angles HDG and HFE are alternate interior angles, which lead to showing DG is parallel to EF.

State the practical meaning of the slope and y-intercept for the situation described. The cost, in dollars, of retaining the services of a computer repairman in Anchorville is given by C = 48x + 18, where x is the number of hours worked. a. 48 signifies the hourly rate, and 18 signifies the overhead charge. c. 18 signifies the hourly rate, and 48 signifies the overhead charge. b. -48 signifies the hourly rate, and 18 signifies the travel cost.

Answers

The practical meaning of the slope and y - intercept of the linear equation, C = 48x + 18 is that 48x is the variable cost depending on the number of hours and 18 is the fixed cost or the overhead change. Hence, the answer to the question above is letter A.
