Answer:
C)
B)
C)
Step-by-step explanation:
<h3>Question-1:</h3>
recall the surface area formula of cylinder
given that,h=5 and r=0.7
substitute:
simplify parentheses:
simplify multiplication:
hence, our answer is C
<h3>Question-2:</h3>
remember the surface area formula of cone
given that,r=7 and s=10
substitute:
simplify parentheses:
simplify multiplication:
hence, our answer is B
<h3>Question-3:</h3>
now for the question-3 we need a little bit understanding
remember the surface area formula of cube
we are given that, Thus
substitute:
divide both sides by 6:
square root both sides:
hence, the measurement of each
edge is 10 cm therefore our answer is C)
This is true? I don't exactly understand....
The ratio is 2:50 (Reduced 1:25) I hope this helped ^^
Answer:
none
Step-by-step explanation:
110 + 60 = 170
but 170 is obviously not 180 sooo none will be 60 degrees
Answer:
Step-by-step explanation:
1. Equation: x + 50 = 180 degrees
Solution: x = 180 - 50
x = 130 degrees
2. Equation: x + 45 = 90 degrees
Solution: x = 90 - 45
x = 45 degrees
