Answer 2

Answer:

Step-by-step explanation:

Let's start with the area of semi circle :

r=radius,h=height,d=diameter.

So now we should start:

r of semi circle =10th

So pie r^2

=1/2*22/7*10*10

=1100/7cm^2

So now area of triangle

Base=20cm

h=20cm(because h of triangle is formed on diameter of hemisphere so h =d and 2r=d, r=10th so 2*10=d and d=20cm, d=h so h=20cm.)

=1/2*b*h

=1/2*25*20

=1/1*25*10

=25*10

=250cm^2

Area of hemisphere+Area of triangle=Area of fig

1100/7+250=Area of fig

2850/7=Area of fig

407.14=Area of fig

So

Area of fig is 407.14
