Answer:21.99
Step-by-step explanation: Given diameter of a circle is(d)=7cm.
Now, we know that circumference of circle is =πd, where d is diameter of circle.
So, here circumference is = π×7cm
= 22/7 x 7 cm
Circumference = 22cm
Answer:
The answer is (B) ⇒ Yes. AB is parallel to CD and AD is parallel to BC
Step-by-step explanation:
<em>There is an important fact about the parallel lines: </em>
- Parallel lines have equal slopes
<em>The rule of the slope of a line is:</em>
, where 
and 
are two points on the line
<em>Let us use the fact and the rule to solve the question</em>
∵ ABCD is a quadrilateral
∵ A = (0, 2) , B = (2, 6), C = (9, 6), D = (7, 2)
∵ The opposite sides are AB, CD and AD, BC
Find the slopes of the four sides to check the parallel sides
∵ 
∵ 
∵ The slope of AB = The slope of CD
∴ AB // CD
∵ 
∵ 
∵ The slope of AB = The slope of CD
∴ AD // BC
The correct answer is:
Yes. AB is parallel to CD and AD is parallel to BC ⇒ (B)
Answer:
Option B
Step-by-step explanation:
The reason is because the surface area is not including the base of the pyramid and the top of the prism.
Option b. she left out one of the faces of the solid she should have simplified 2((5)(7))+2((6)(7))+2[1/2(5)(9.3)]+2[1/2(6)(9.2)]+(5)(6)
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the pyramid not including the base plus the surface area of the prism not including the top
so
SA= 285.7 units squared
Answer:
Rectangle= Choice four
Square= Choice three
Trapezoid= Choice one
Parallelogram= Choice two
Rhombus= Choice five
