What is the best approximation for the area of a circle with a diameter of 13 meters?

1 answer:

4 0

First, find the radius of the circle. The radius of a circle is half the diameter. r=13/2=6.5

Second, use the equation A=pi * r^2 to find the area of the circle.
A=(3.14) * (6.5^2) = 132.665m^2

so the answer is 132.7 m^2.

Line AC and line DB intersect at point P. Solve for angle BPQ.

taurus [48]

Answer:

Angle BPQ = 64°

Step-by-step explanation:

4x + 12 +2x = 90

6x + 12 = 90

- 12 -12

6x = 78

x = 13°

BPQ = ((4(13) + 12)°

(52 + 12)°

64°

Find the distance between (3,4) and (4,-6) if necessary, round to the nearest tenth.

Ratling [72]

Answer:

The distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Step-by-step explanation:

Given the points

(3,4)

(4,-6)

The distance 'd' between (3,4) and (4,-6)

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):$

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting the points values

$=\sqrt{\left(4-3\right)^2+\left(-6-4\right)^2}$

$=\sqrt{1+10^2}$

$=\sqrt{1+100}$

$=\sqrt{101}$

$=10.0$ units (Rounded to the nearest the Tenths Place)

Thus, the distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Angle M has a measure between 0° and 360° and is coterminal with a –620° angle. What is the measure of angle M?

kirill [66]

Negative angles are measured clockwise from 0 degrees.

620 = 360 + 260

260 clockwise = 100 degrees anticlockwise

co terminal angle is 100 degrres
