The circumference of a circle is 24 feet. What is the approximate length of the radius? Round to the nearest tenth

jarptica [38.1K]

<h3>given:</h3>

circumference= 24 feet

the radius of the circle.

<h3>solution:</h3>

$c = 2\pi \: r$

$r = \frac{c}{2\pi}$

$r = \frac{24}{2 \times \pi}$

$r = 3.81972$

$r = 3.8 \: ft$

therefore, the radius of the circle is 3.8 feet.

Suppose that you measure a pen to be 10.5cm long. Convert this to meters.

Vinvika [58]

the answer: the following methods are the main rule according to the convertions we know this followin table: km hm dam m dm cm mm. if we want to change or convert any value, cm to meters, meters to km, or anything else, just follow this: converting dm (decimeter) to m, just multiply the number by 0.1, converting cm (centimeter) to m, just multiply the number by 0.01, converting mm (millimeter) to m, just multiply the number by 0.001, in our case, we have: convert 10.5cm to meters, so it is 10.5 x 0.01 =0.105 meters

ZA and ZB are complementary angles. If mZA = (2x + 10)° and m

fiasKO [112]

Answer:

∠ZB = 54°

Step-by-step explanation:

Given:

Pair of complementary angles

∠ZA = (2x + 10)° and m

∠ZB = (3x + 15)

Find:

Measure of ∠ZB

Computation:

complementary angles

a + b = 90°

∠ZA + ∠ZB = 90°

(2x + 10) + (3x + 15) = 90

5x + 25 = 90

x = 13

So,

∠ZB = (3x + 15)

∠ZB = 13(3) + 15

∠ZB = 54°

Dmitri wants to cover the top and sides of this box with glass tiles that are 1 cm square. How many tiles will he need? Dmitri w

marta [7]

The number of tiles needed to cover the surface area of the box excluding the bottom is: 1,046 tiles.

<h3>What is the Surface Area of a Box?</h3>

The surface area of a box is the area surrounding all its faces. A box has 6 rectangular faces. Therefore, the total surface area of the box equals the sum of all 6 rectangular faces.

<h3>What is the Surface Area of a Box?</h3>

SA = 2(lw + lh + hw), where:

l = length
w = width
h = height of the box

The image attached below shows the box Dmitri wants to cover. Since the bottom of the box would be excluded, therefore:

The surface area to be covered = surface area of the box - area of the bottom rectangular face

The surface area to be covered = 2(lw + lh + hw) - (l)(w)

l = 26

w = 15

h = 8

Substitute

The surface area to be covered = 2(l×w + lh + hw) - (l)(w) = 2·(15·26+8·26+8·15) - (26)(15) =

The surface area to be covered = 1436 - 390 = 1,046 cm

Area of one tile = 1 cm square

Number of tiles needed = 1,046/1

Number of tiles needed = 1,046 tiles.
