What is the volume of the square pyramid? Round to the nearest tenth

Mathematics

Answer:

The correct option is 3.

Step-by-step explanation:

The volume of a square pyramid is

V=\frac{1}{3}(\text{Base area})h

V=\frac{1}{3}a^2h                  .... (1)

Where, a is th side of base and h is the height of pyramid.

From the given figure it is clear that the height of the pyramid is 10 cm and the  length of base is 12 cm.

Substitute a=12 and h=10 in equation (1), to find the volume of the square pyramid.

V=\frac{1}{3}\times (12)^2\times (10)

V=\frac{1}{3}\times (144)\times (10)

V=(48)\times (10)

V=480

The volume of pyramid is 480 cm³. Therefore the correct option is 3.

ANSWER

Volume = 480.0{cm}^{3}

EXPLANATION

The volume of the square pyramid is given by;

Volume =  \frac{1}{3}  {l}^{2} \times  h

Where l=12cm is the length of the square base and h=10cm is the height of the pyramid.

We substitute the values into the formula to get;

Volume =  \frac{1}{3}  \times  {12}^{2} \times  10 {cm}^{3}

This simplifies to,

Volume =  \frac{1}{3}  \times  {12} \times 12\times  10 {cm}^{3}

Volume = 4 \times 12\times  10 {cm}^{3}

Volume = 480.0{cm}^{3}

Third option is correct.

Answer:

946

Step-by-step explanation:

we know that

The formula to find the sum is equal to

S=(a1+an)n/2

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

n=11

a1=(98-2(1))=96

an=(98-2(11))=76

substitute the values in the formula

S=(96+76)(11/2)=946

How many revolutions will a car wheel of diameter 22 in. make as the car travels a distance of one mile
Marianna [84]

It would be take upto 999 revolutions.

<em>Let try to solve it,</em>

Let n represent number of revolutions.

We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.

1 mile = 63360 inches.

We will use circumference of circle formula to solve our given problem.

Circumference = pi*d , where, D represents diameter of circle.

Now, we will set the product of n and circumference of circle equal to 63360 inches as:

pi*22*n= 63360

n= 63360*7/ 22*22

n= 443520/444

n= 998.91

Therefore It would be take upto 999 revolutions.
