What is the area of this circle? (Express your answer using π.)
(Note: The diameter is 10ft.)

Answers

Answer 1
Answer: The area is πr².
The radius r is half the diameter. The diameter is 10 ft so the radius is 5 ft.

A=\pi * 5^2=25 \pi

The area is 25π ft².
Answer 2
Answer: Area of a circle is:

A = pi * r^2

If the diameter is 10 feet, the radius will be half of that or 5.

So:

A = 3.14 * 5^2

Simplify exponent:

A = 3.14 * 25

Multiply:

A = 78.5

What is the difference of 7x − (25x2 + 12x)

Answers

If you would like to solve 7x - (25x^2 + 12x), you can do this using the following steps:

7x - (25x^2 + 12x) = 7x - 25x^2 - 12x = - 25x^2 - 5x

The correct result would be - 25x^2 - 5x.

A model ship is 28 in. by 65 in Use the scale in : 1/2ft to find the dimension of the actual ship

Answers

Answer: The actual ship is 168 in by 390 in

Step-by-step explanation:

The model ship is:

28 in by 65 in.

The factor of scale is 1/2 ft, this means that each inch corresponds to 1/2 ft, so we have that the actual scale is:

28 in*(1/2 ft/in) = 28*(1/2)ft = 14ft

by:

65in*(1/2ft/in) = 32.5ft

So the ship is 14ft by 32.5 ft, and knowing that 1 ft = 12 inches, we can write this in inches as:

14*12 in = 168 in

32.5*12 in = 390in.

The actual ship is 168 in by 390 in
