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)
