Total surface area: approximately 979.3 inches squared (total), 754.3 inches (lateral), and 225 inches (bottom)
Hello,
tan KLJ=6/8=3/4
=> mes angle KLJ=36.8698976558...°≈36.87 °
Answer B.
Answer:
one solution (-2 ; 5)
Step-by-step explanation:
hello : 2x + 3y= 11
...(*)
-x-5y=-23.....(**)
by(**) : x= -5y+23
put this value into (*) : 2(-5y+23)+3y=11
-10y+46+3y=11
-7y = -35
y=5
but x= -5y+23
so : x= -5(5)+23 =-2
To solve for the value of y, all you have to do is add up all the expressions and values together and make it equal to 180 degrees.
Y + (Y - 12) + 56 = 180
2Y - 12 + 56 = 180
2Y + 44 = 180
Y = 68 degrees.
Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :
When r = 5.05, new volum becomes,
Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².
