Naya [18.7K]

Answer:

No, Mai's reasoning is incorrect

Step-by-step explanation:

They are actually going the same speed because their centimeter per second ratio is the same. this can be found by dividing them both down, divide the slug by three and the snail by 6 and they both end up the same centimeter/second ratio. (1:1)

Sorry idk how to explain it good but do you get it?

Area of a circle with a circumference of 18.84
podryga [215]

Answer:

The area of a circle with a circumference of 18.84  is 28.26 units²

Step-by-step explanation:

Given:

Circumference = 18.84

Let R be the Radius of a Circle

pi = 3.14

To Find:

Area of Circle = ?

Solution:

We Know that,

Circumference = 2\pi Radius

Substituting the values we get the radius

18.84=2\times 3.14\times Radius\\\\18.84 = 6.28\times Radius\\\\\therefore Radius =\frac{18.84}{6.28} \\\\\therefore Radius = 3\ unit\\

Now Formula for calculating Area of Circle is given as

\textrm{Area of Circle} =\pi (Radius)^{2}

Substituting the Radius we get

\textrm{Area of Circle} =3.14\times 3^{2}\\\\\textrm{Area of Circle} =28.26\ units^{2}

The area of a circle with a circumference of 18.84  is 28.26 units²

The sea turtle habitat at the zoo is made by connecting two large aquariums. The first aquarium is 6\text { m}6 m6, space, m lon
iren [92.7K]

First aquarium dimensions:

Length = 6 m.

Width = 4 m and

Height = 2 meter.

Second aquarium dimensions:

Length = 8 m.

Width = 9 m and

Height = 3 meter.

We know formula for volume of a cuboidal box = Length*Width*Height.

Plugging values of length, width and height of first aquarium in formula of volume. We get

V1 = 6*4*2 = 48 m^3.

Plugging values of length, width and height of second aquarium in formula of volume. We get

V2 = 8*9*3 = 216 m^3.

In order to find the total cubic meters of space do the sea turtles have in their habitat, we need to add both volumes.

Therefore, Total voulme of both aquarium = V1 +V2 = 48+216 = 264 m^3.

Therefore, total 264 m^3 cubic meters of space the sea turtles have in their habitat.
