Answer:
Step 1
Step-by-step explanation:
they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
Answer: D ) 24
Answer:
Volume of this cylinder = 785.71 Cm³
Surface area of this cylinder = 157.14 Cm²
Step-by-step explanation:
Given:
Height of cylinder = 10 Cm
Radius of cylinder = 10 / 2 = 5 Cm
Find:
Volume of this cylinder.
Surface area of this cylinder
Computation:
Volume of this cylinder = πr²h
Volume of this cylinder = (22/7)(5)²(10)
Volume of this cylinder = 785.71 Cm³
Surface area of this cylinder = 2πr(h+r)
Surface area of this cylinder = 2(22/7)(5)(10+5)
Surface area of this cylinder = 2(22/7)(5)(15)
Surface area of this cylinder = 157.14 Cm²
