Answer:

A beach ball is a sphere, so we will need to know how to find the volume of a

sphere. V = 4Pi * (r ^ 3 / 3)

We have the diameter, but not the radius. To find the radius, it is half of the

diameter.

10÷2=5 Now let's plug it in.

4T(5³/3) Let's solve.

4pi = 12.56

5³= 125

125÷3= 41.67 (repeating 6) 41.67x12.56=523.3752

523.33 cubic inches is the volume of

air contained inside the beach ball. The reason I picked that answer is because a repeating 6. So we should expect for

we rounded up to 41.67, when there was

the answer to be a couple decimals lower

from the answer we got. Tell me if this helps!!

Mandy built a pyramid for her project on Egypt with a volume of 483
emmainna [20.7K]

Answer

We have,

Volume of pyramid = 4834 in³

Base area of the pyramid = ?

Assuming height of the pyramid = 20 in

We know that

Volume of pyramid =\dfrac{hlw}{3}  

           4834=\dfrac{20\time lw}{3}  

           l w = 725.1 in²

Hence, area of the base of the pyramid is equal to 725.1 in².

PLZ HELP ASAP WILL MARK BRAINLIEST
RSB [31]

Answer:

72\sqrt{3}

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = \frac{1}{2} × d₁ × d₂ (d₁ and d₂ are the diagonals )

The diagonals bisect each other at right angles

d₁ = 2 × 6 = 12

Use the tangent ration in the upper left right triangle and the exact value

tan60° = \sqrt{3}

tan60° = \frac{opposite}{adjacent} = \frac{opp}{6} = \sqrt{3} ( multiply both sides by 6 )

opp = 6\sqrt{3} , then

d₂ = 2 × 6\sqrt{3} = 12\sqrt{3}

Thus

A = \frac{1}{2} × 12 × 12\sqrt{3} = 6 × 12\sqrt{3} = 72\sqrt{3}
