Question

please solve me this so that I can learn ​

Answer 1

Step-by-step explanation:

Let's calculate area of fig first

It's a semicircle

So area will be

πr^2× 1/2

3.14 × 100/2

314/2

157 sq cm

area of triangle =

1/2× b×h

1/2 × 8×6

4×3

12 sq cm

so area of shaded region will be =

total area - area of triangle

157 -12

145 sq cm

Answer 2

Answer:

AREA OF THE SHADED FIGURE=AREA OF SEMICIRCLE-AREA OF TRIANGLE

AREA OF SEMICIRCLE=πr²/2= 22/7 * 5*5/2=22/7 *25 /2=39.29cm²

area of ²Δ= 1/2 *base*height= 1/2 * 8*6=24cm²

area of shaded figure=(39.29-24)cm²=15.29 cm²
