Answer:
Step-by-step explanation:
Surface area of sphere = 125 sq.ft
4πr² = 125
4*3.14*r² = 125
r = 3.15 ft
Yes because if you divide 17 by 15 you get about 1.133 and if you divide 68 by 60 you also get about 1.133
Answer:
Assuming π is represented by 3.14, the correct answer is 
.
Step-by-step explanation:
Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is 
, where r is the radius of the circle. Since the radius of the shaded circle is 
, you can infer that the area of the shaded region would be 
= 
= .
Answer:
D) 2
Step-by-step explanation:
Use the following slope formula:
<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (4 , 1)
(x₂ , y₂) = (1 , -5)
Plug in the corresponding numbers to the corresponding variables:
<em>m</em> = (-5 - 1)/(1 - 4)
Simplify. Remember to follow PEMDAS. First subtract, then divide:
<em>m</em> = (-5 - 1)/(1 - 4)
<em>m</em> = (-6)/(-3)
<em>m</em> = 2
D) 2 is your answer.
