Let First Sphere be the Original Sphere
its Radius be : r
We know that Surface Area of the Sphere is : 4π × (radius)²
⇒ Surface Area of the Original Sphere = 4πr²
Given : The Radius of Original Sphere is Doubled
Let the Sphere whose Radius is Doubled be New Sphere
⇒ Surface of the New Sphere = 4π × (2r)² = 4π × 4 × r²
But we know that : 4πr² is the Surface Area of Original Sphere
⇒ Surface of the New Sphere = 4 × Original Sphere
⇒ If the Radius the Sphere is Doubled, the Surface Area would be enlarged by factor : 4

Answer: 6 sandwiches
Step-by-step explanation:
To get the amount of roast beef that Marissa used you would have to subtract 2 3/4 from 5...which is 2.25 pounds of beef that she used.
Then you would divide 2.25 by 3/8 which is 6... meaning Marisa made 6 sandwiches!
Answer:
-1/12x
Step-by-step explanation:
Let total people at the picnic=x
People who chose apple= 1/3x
People who chose orange= 3/4x
People who chose each of the fruit= People who chose apple + People who chose orange
=1/3x + 3/4x
= 4x+9x / 12
=13/12x
People who chose each of the fruit= 13/12x
what fraction of the people chose both of them?
Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit
=x - 13/12x
=12x- 13x /12
= -1/12 x
