Answer:
cylinder surface area = 201.06in²
surface area of cone = 56.56in.²
Step-by-step explanation:
cylinder surface area formula = 2πrh + 2πr²
refer the pic
cone surface area formula = πr ( r + √h² + r² )
refer the sec pic
surface area of the solid
= ( 201.06 + 56.56 ) in.²
= 257.62in.²
= 258in.²
Answer:
I'm not so sure about this one so sorry if this is wrong
Step-by-step explanation:
5x+34=-2(1-7x)
Steps:
5x+34=-2+14x
5x+34-14x= -2
-9x + 34= -2
-9x = -2-34
-9x = -36
X= -36/-9
Answer: x= 4

Answer:
Height = 13.86 cm
Step-by-step explanation:
1. Find the length of each side
48/3 = 16
2. cut the triangle in half.
Base = 8 Hypotenuse = 16
3. use the formula A^2 + B^2 = C^2
(16^2 - 8^2)^(1/2) = 13.86 cm
