Answer:
2.48 cubic inches
Step-by-step explanation:
This is very simple. We need to find the volume of a sphere.
THe formula of volume of a sphere is given by:
Where
V is the volume, and r is the radius
We know radius is HALF of diameter, so r = 1.68/2 = 0.84
<em>Now, we plug in the info given into the formula and figure out the answer:</em>
<em></em>
<em>The answer is: the volume is 2.48 cubic inches</em>
The answer is 160 hope that helped
Radius of the circle "" = 5.5 yd
The area of the given figure.
We know that,
=
Using 3.14 for π, we have
Using for π,
Therefore, the area of the semi-circle is .
<u>ANSWER: </u>
Carlos is building a screen door.The width of the screen is 3 feet.
<u>SOLUTION:
</u>
Given, Carlos is building a screen door. The height of the door is 1 foot more than twice its width.
And height of the screen door is 7 feet high.
Let the width of the screen door be x feet wide.
Now, according to given information,
Height is 1 foot more than the 2 times of width. Hence we can form a equation as,
7 = 1 + 2x
2x = 7 – 1
2x = 6
x = = 3
Hence, the width of the screen is 3 feet.
