If a radius of a circle is 12 feet, what is the area and perimeter of the circle?

Answers

Answer 1

Answer: area of a circle=πr²
area of this cirlce=π*(12 ft)²=144π ft²≈452.39 ft².

answer 1= the area of this circle is 452.39 ft².

Perimeter of a circle=2πr.
Perimeter of this cirlce=2π(12 ft)=24π ft≈75.4 ft

answer 2= the perimeter of this cirlce is 75.4 ft.

Answer 2

Answer:

Answer:

Area: 452.4

Perimeter: 75.4 ft

Step-by-step explanation:

Formula for area: $\pi r^(2)$

Formula for perimeter: $\pi d$ or $2\pi r$

Which of the following points is the greatest distance from the origin? (1,6)
(2,6)
(4,5)
(5,1)

Answers

The point which is farthest from the origin is required.

The point which is the greatest distance from the origin is $(4,5)$

Distance from origin

The distance of a point from origin is given by

$d=√(x^2+y^2)$

$(1,6)$

$d=√(1^2+6^2)\n\Rightarrow d=√(37)\ \text{units}$

$(2,6)$

$d=√(2^2+6^2)\n\Rightarrow d=√(40)\ \text{units}$

$(4,5)$

$d=√(4^2+5^2)\n\Rightarrow d=√(41)\ \text{units}$

$(5,1)$

$d=√(5^2+1^2)\n\Rightarrow d=√(26)\ \text{units}$

The largest number is $√(41)$
