If there was a circle and i wanted to find out the area.

1 answer:

6 0

The formula for the area of a circle is πr^2
r means radius.
If the radius is 5, then r = 5.
This means the equation for the area is π(5)^2
π is about equal to 3.14.
So we can replace π with 3.14.
(3.14)(5)^2
According to the order of operations, the first step to solve this is to do 5^2, which is exponents.
5^2 = 25
Next, multiply.
25 • 3.14 = 78.5
So the area of the circle with a radius of 5 is approximately 78.5 square units.

Answer:

$x = 23$

Step-by-step explanation:

Given, $\frac{x - 5}{2} = 9$ , solve for x.

Multiply both sides by 2

$\frac{x - 5}{2} \times 2 = 9 \times 2$

$x - 5 = 18$

Add x to both sides

$x - 5 + 5 = 18 + 5$

$x = 23$

Convert the polar coordinates (120.2, 119°) into rectangular coordinates. Round the rectangular coordinates to the nearest hundr

Alchen [17]

The conversion is
x = magnitude × cos(angle)
y = magnitude × sin(angle)
or
(x, y) = 120.2(cos(119°), sin(119°)) ≈ (-58.27, 105.13)
