How do you find the radius and diameter with the circumference

Mathematics
1 answer:
Levart [38]3 years ago
6 0
Ok

relation of diameter to radius
2 radius=1diameter
radius=1/2 diameter
2r=d
d/2=r


circumfernce=2pir
since 2r=d
circumference=2d

so
c=pid=2pir

so if ou have circunference and you want to find diameter and radius
c=pid
divde both sides by pi
c/pi=d

c=2pir
divide both sides by 2pi
c/(2pi)=r


so
r=c/(2pi)
d=c/pi

PLEASE HELP WHAT IS THE ANSWER SHOW WORK PLEASE !!!
Mrac [35]

Answer:

d = 6.1m

n = 7km

Step-by-step explanation:

To find the variables, use tan

⇒ tan = \frac{opposite}{adjacent}

finding d:

⇒tan 63 = \frac{d}{3.1}

tan of 63 is 1.963

⇒ 1.963 = \frac{d}{3.1}

multiply 3.1 on both sides

⇒ 1.963 x 3.1 = \frac{d}{3.1} x 3.1

⇒ 6.0853 = d

round to the nearest tenth:

⇒ 6.0853 = 6.1

finding n:

⇒ tan 45 = \frac{7}{n}

tan of 45 is 1

⇒ 1 = \frac{7}{n}

multiply 7 on both sides:

⇒ 1 x 7 = \frac{7}{n} x 7

7 = n

The diagram shows a cuboid.<br> 4 cm<br> 5 cm<br> 9 cm<br> What is the surface area of the cuboid?
katrin2010 [14]

Answer:

202 cm^2

Step-by-step explanation:

SA = 2LW + 2LH + 2WH

SA = 2(4 cm)(5 cm) + 2(4 cm)(9 cm) + 2(5 cm)(9 cm)

SA = 40 cm^2 + 72 cm^2 + 90 cm^2

SA = 202 cm^2

If point p partitions line BA,what would be the part to whole ratio
IRINA_888 [86]

Answer:

4 / 5

Step-by-step explanation:

From the image attached, Line BA is divided into a total of 5 equal proportions (or intervals). Point P is placed at the 4th proportion of the divided line, also the distance between point P and point A is 1 propotion. The ratio in which point P divides the line BA is given as:

Ratio = BP : PA = 4 : 1

Ratio = 4 : 1

The part to whole ratio If point p partitions line BA = BP / BA = 4 / 5

Part to whole ratio = 4/5
