What is the circumternence

1 answer:

AfilCa [17]3 years ago

4 0

Circumference of a circle is the distance around the circle. This can be found by using the equation below

2*pi*radius

Our diameter, as shown, is 9cm. Since radius is half of the diameter, our radius is 4.5cm.

Therefore, our circumference is...

2 * pi * 4.5 = 9pi cm total

Find the value of x.

Allisa [31]

A straight line is 180°, so you can do:

109 + ? = 180 (? is the top angle of the triangle)

? = 71°

Because the triangle is an isosceles triangle, the other angle is 71° too.

71 + 71 + ? = 180

? = 38

You subtract 38 with 90 to find the other angle.

90 - 38 = 52°

To find ∠2 you subtract 52 with 180.

180 - 52 = 128

∠2 = 128

128 = 11x + 18

110 = 11x

10 = x

<u>Given</u>:

Given that the radius of the sphere is 9 cm

We need to determine the volume of the sphere.

<u>Volume of the sphere:</u>

Let us determine the volume of the sphere.

The volume of the sphere can be determined using the formula,

$V=\frac{4}{3} \pi r^3$

where r is the radius of the sphere.

Substituting r = 9 in the above formula, we get;

$V=\frac{4}{3} \pi (9)^3$

$V=\frac{4}{3} \pi (729)$

$V=\frac{2916}{3} \pi$

$V=972 \pi$

Thus, the volume of the sphere is 972π cm³

Hence, Option B is the correct answer.
