Answer:
6 3/8
Step-by-step explanation:
<span>B) the bisectors of angles D, E, and F
</span>
In an inscribed circle of a triangle, all angle bisectors will pass through the center of the circle.
Pls. see attachment.
1st attachment is Triangle DEF. 2nd attachment is how inscribed circle relates to the triangle it is inscribed in.
To find the height you need to take the volume, and the radius (halve the diameter to get the radius) and use the same formula that would be to find Volume and when you plug in the volume and radius you take the radius and solve it with the exponent. Then you take the solved radius and you multiply it with 3.14. After that you then divide the volume by the multiplication.
V=(3.14)(r^2)h
Example:
V=87.92m^3
pi=3.14
r=2m
h=?
87.92=(3.14(2)^2)h
87.92=(3.14(4))h
3.14*4=12.56
87.92/12.56=7
h=7m
Answer:
(B)
Step-by-step explanation:
Let us denote rectangular tiles by R and square tile by S, then
According to figure.
3 rectangular tiles +2 square tiles +2 square tiles =2 rectangular tiles +4 square tiles +1 rectangular tiles +4 square tiles
∴3R+2S+2R=2R+4S+R+4S
⇒5R+2S=3R+8S
⇒5R-3R=8S-2S
⇒2R=6S
⇒R=3S
Hence, 0ne rectangle =3 square
