What is the area of circle with a diameterms of 10 m

1 answer:

pentagon [3]3 years ago

6 0

Answer:

exact area = 25(pi) m^2

approximate area = 78.54 m^2

Step-by-step explanation:

diameter = 10 m

radius = diameter/2 = 10 m / 2 = 5 m

area = (pi)r^2

area = (pi)(5 m)^2

area = 25(pi) m^2

area = 78.54 m^2

The function A(b) relates the area of a trapezoid with a given height of 14 and one base length of 5 with the length of its othe

Brut [27]

Answer:

$b(a) =\frac{a}{7} -5$

Step-by-step explanation:

Given

$A(b) = 14 * \frac{b + 5}{2}$

Required

Determine the inverse function b(a)

Write A(b) as a

$a = 14 * \frac{b + 5}{2}$

Swap a and b

$b = 14 * \frac{a + 5}{2}$

$b = 7(a + 5)$

Divide both sides by 7

$a + 5 = \frac{b}{7}$

Maka a the subject

$a =\frac{b}{7} -5$

Swap a and b again

$b =\frac{a}{7} -5$

Hence:

$b(a) =\frac{a}{7} -5$

One end of a line segment has the coordinates (-6,2). If

CaHeK987 [17]

Answer:

The coordinates of the other end is $(16,2)$

Step-by-step explanation:

Given

$End 1: (-6,2)$

$Midpoint: (5,2)$

Required

Find the coordinates of the other end

Let Midpoint be represented by (x,y);

(x,y) = (5,2) is calculated as thus

$(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$

So

$x = \frac{x_1 + x_2}{2}$ and $y = \frac{y_1 + y_2}{2}$

Where $(x_1,y_1) = (-6,2)$ and $(x,y) = (5,2)$

So, we're solving for $(x_2,y_2)$

Solving for $x_2$

$x = \frac{x_1 + x_2}{2}$

Substitute 5 for x and -6 for x₁

$5 = \frac{-6 + x_2}{2}$

Multiply both sides by 2

$2 * 5 = \frac{-6 + x_2}{2} * 2$

$10 = -6 + x_2$

Add 6 to both sides

$6 + 10 = -6 +6 + x_2$

$x_2 = 16$

Solving for $y_2$

$y = \frac{y_1 + y_2}{2}$

Substitute 2 for y and 2 for y₁

$2 = \frac{2 + y_2}{2}$

Multiply both sides by 2

$2 * 2 = \frac{2 + y_2}{2} * 2$

$4 = 2 + y_2$

Subtract 2 from both sides

$4 - 2 = 2 - 2 + y_2$

$y_2 = 2$

$(x_2,y_2) = (16,2)$

Hence, the coordinates of the other end is $(16,2)$
