1 answer:
Vinil7 [7]3 years ago
5 0

Answer:

Perimeter b = circumference b = 10π; Area b = 50π

Perimeter c = circumference c = 10.5π; Area b = 27π

Step-by-step explanation:

b. Circumference = perimeter

Circumference of semicircle= πr=10π =Perimeter

Area of semi circle=πr^2/2=10^2π/2=50π

c. Circumference = 7/4πr=1.75*6π=10.5π=Perimeter

Area of the diagram = 3/4πr^2=0.75π*6^2=0.75π*36=27π

Is A ABC similar to DEF? Why or why not?
vova2212 [387]

Answer:

Option(D)

Step-by-step explanation:

Given are the two triangles, that are ABC and DEF, in which AB=8ft, DE=6ft, AC=10ft and DF=7.5ft.

For the two triangles to be similar, it must satisfy the similarity condition that is:

Both the triangles must have congruent angles and the sides should be proportional. Since, two sides of the given triangles are not proportional.Moreover, ∠A=25° and ∠D=24° which are not equal and ∠C=60° and ∠F=61° which are also not equal.

Therefore, Not all the angles are congruent, thus the triangles cannot be similar.
