Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC
Hypotenuse ^2 = 8^2 + 21^2
hypotenuse =
=
=
= 22.47
So the length of the hypotenuse is 22.47 m
Answer:
29°
Step-by-step explanation:
151° + a=180°
We know the sum of angles in a straight line is 180°
a= 180°-151°
The sign changed as it changed sides
a= 29°
The SA of a sphere is 4 times the area of the base of if you cut it in half. So that would mean that that would be (9/4)pi yd2. Pi*r^2=area of a circle, so that means the radius is 3/2 yds.
<span>The volume of a sphere is (4/3)*pi*r^3. If we plug in the radius, we get: </span>
<span>(4/3)*pi*(3/2)^3 </span>
<span>(4/3)*pi*(27/8) </span>
<span>(27/6)pi, or 4 and 1/2 pi </span>
<span>If you want an actual number with pi used, you get about 14.137166952</span>
Can you take a picture of the problem... because we cant see the shape or any of the angles for that manner.
