s.a=C.A xH
v of n.o.2 =lxwxh
Step-by-step explanation:
v of no.3=πr2h and s.a=πdh
no.1=area of cross section x area of all faces and v=area of cross section x length
try those ones
Step-by-step explanation:
It is possible
One person will get 246 while the other will get 266 = 512
Answer:
Angle BCA = 70
Angle CAB = 20
Step-by-step explanation:
Not sure what angle you meant, so I'll give you all of them <3
Angle BCA = 70 degrees, because If two angles form a line, they add up to 180. (110+x=180, x = 70)
Angle CAB = 20 degrees, because there are 180 degrees in a triangle, so 90+70+x=180, x = 20
Hope it helps <3
Answer:
l = 10 feet, m = 30 feet and n = 25 feet
Step-by-step explanation:
The attached figure shows a triangle in which three sides as as follows :
, m and 
Perimeter of triangle is 65 feet.
Perimeter = sum of all sides
put the value of n
Now put the value of l
⇒ 
And
Hence, l = 10 feet, m = 30 feet and n = 25 feet.
Ok, I'm only in 8th grade but I believe you do addition first in the problem. Hope this helps! <3
