Find the area of the semi circle with Diameter of 4

Mathematics
1 answer:
daser333 [38]3 years ago
6 0

Answer:

Find the area of the semi circle with Diameter of 4

2π

6.3

Step-by-step explanation:

The area formula for semicircle is (πr^2)/2.

r=2 because radius is half of diameter.

(π(2)^2)/2, 2 squared= 4 and half of it is 2. = 2π

2π would round to the nearest tenths is 6.3.

Why we have exactly six trignomeric
const2013 [10]
A triangle has three sides. A ratio is a comparison of two things. We pick two different sides of the triangle to compare (because there is not much point in comparing one thing to itself). How many ways are there to do this? The first choice has 3 options, and the second has 2, so we have a total of 3\times2=6 possibilities.

Find the volume of the cone whose base is shown and whose altitude is 8 meters.
Aloiza [94]
\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\implies V=\stackrel{base~area}{\pi r^2}\cdot \cfrac{1}{3}\stackrel{height}{h}\\\\
-------------------------------\\\\
\textit{base of this cone}\\\\
B=\stackrel{a~square}{5\cdot 5}+\stackrel{semi-circle}{\frac{\pi r^2}{2}}\implies B=25+\frac{\pi 3^2}{2}\\\\\\ B=\stackrel{square}{25}+\stackrel{semi-circle}{\frac{9\pi }{2}}
\\\\\\
\textit{height of this cone is just 8}\\\\
-------------------------------\\\\

\bf \textit{volume of this cone}\\\\
V=B\cdot \cfrac{1}{3}h\implies V=\left( 25+\cfrac{9\pi }{2} \right)\left( \cfrac{8}{3} \right)
\\\\\\
V=\cfrac{200}{3}+\cfrac{3\pi\cdot 4 }{1}\implies V=\cfrac{200}{3}+12\pi
