Answer: The diameter is 28cm

Step-by-step explanation:

Circumference is 2\pi r where r is the radius or just \pi d where d is the diameter. For this, we'll use the one with the diameter.

87.92=3.14d\\\frac{87.92}{3.14} =\frac{3.14d}{3.14} \\28=d

A 2 cm x 2 cm x 2 cm cube holds 468 grains of rice. How many grains of rice would fit in a box with
Amiraneli [1.4K]
Let the Volume of the first cube be V1

V1 = 2 * 2 * 2

= 8 cm*3


Let the Volume of the second cube be V2

V2 = 6 * 2 * 12

= 144 cm*3


Now, cube1 with volume of 8 cm*3 holds 468 grains of rice.

Thus, 1 cm*3 volume can hold 58.5 grains of rice ( 468 / 8 = 58.5)

Cube2 has volume of 144 cm*3.

Hence, it can hold 8424 grains of rice ( 144 * 58.5 = 8424)

Can't quite figure out the limit problem ​
alisha [4.7K]

Use the squeeze theorem; if

1 - <em>x</em> ²/4 ≤ <em>u(x)</em> ≤ 1 + <em>x</em> ²/2,

then taking the limit on each part as <em>x</em> approaches 0 gives

1 ≤ lim [<em>x</em> → 0] <em>u(x)</em> ≤ 1

and so the limit of <em>u(x)</em> as <em>x</em> → 0 is simply 1.
