Answer:
Unpainted surface area = 514.28 cm²
Step-by-step explanation:
Given:
Side of cube = 20 Cm
Radius of circle = 20 / 2 = 10 Cm
Find:
Unpainted surface area
Computation:
Unpainted surface area = Surface area of cube - 6(Area of circle)
Unpainted surface area = 6a² - 6[πr²]
Unpainted surface area = 6[a² - πr²]
Unpainted surface area = 6[20² - π10²]
Unpainted surface area = 6[400 - 314.285714]
Unpainted surface area = 514.28 cm²
Your answer would be 23.85 but I presume they rounded up so it would be 23.9
48,216 is the answer Idk what laid out means
You subtract (-) 18 from both sides. so 200-18= 182 & 18-18=0. so 182=2m is left. divide both sides by 2 to make the m by itself. 182/2= 91 & 2m/2=1. 91=m
