Answer:
361.7cm²
Step-by-step explanation:
Volume of sphere 1= 8cm³
=
Volume of sphere 2 = 647cm³
But volume of sphere = 4/3πr³
The radius of sphere 2
647 = 4/3πr³
((3*647)/4)/π= r³
5.36544 = r
Surface area = 4πr²
Surface area for the big sphere
= 4π5.36544²
= 361.7cm²
14*4=56+1 for the 40 cents = 57 is your Answer
Answer:
736 Newtons
Step-by-step explanation:
Given
Pressure = 
Multiply both sides by Area
Area × Pressure = Force
Area = 2.3 × 1.6 = 3.68 m², hence
Force = 3.68 × 200 = 736 Newtons
So given l = x+5 and w = x
area represented by equation x^2 +5x = 300
x^2 +5x -300 =0
(x+20)(x-15)=0
x+20 =0
x = -20
x-15=0
x=15
so from these result the width of rectangle equal 15 inches and the length of rectangle equal 20 inches
3z < 30 - 6
3z < 24
z< 24/3
z< 8
answer is z < 8
