Hey there! :D

Plug it into the Pythagorean theorem.

a^2+b^2= c^2

a^2+16^2= 65^2

Square the numbers.

a^2 + 256= 4225

Subtract 256 on both sides.

a^2= 3969

Find the square root of 3969.

a= 63

I hope this helps!

Given:

A figure that contains a right triangular prism and cuboid.

To find:

The volume of the figure.

Solution:

The dimensions of cuboid are 16 in, 7 in and 3 in.

So, the volume of the cuboid is:

$V_1=Length\times Width \times height$

$V_1=16\times 7 \times 3$

$V_1=336$

The base of the prism is a right angle with base 3 in and height 5 in, and the length of the prism is 6 in. So, the base are of the prism is

$B=\dfrac{1}{2}\times Base\times Height$

$B=\dfrac{1}{2}\times 3\times 5$

$B=7.5$

The volume of a prism is:

$V_2=Bh$

Where, B is the base area and h is the height of the prism.

$V_2=(7.5)(6)$

$V_2=45$

The volume of combined figure is:

$V=V_1+V_2$

$V=336+45$

$V=381$

Therefore, the volume of the figure is 381 cubic in.

The area of the bottom of a circular pool 452.2 ft2. What is its circumference, rounded to the nearest tenth?

Alborosie

The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.

To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.

To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.

Finally, round the number you get to the nearest tenth.
