Answer:
308cm²
Step-by-step explanation:
R = 14 cm
So , area of the semicircular disc
= 22/7 × 14cm × 14cm ÷ 2
= 22 × 2cm × 7cm
= 22 × 14cm
= 308cm²
To solve this problem , I did the following :—
- Found the radius of the disc by dividing the diameter by half .
- Applied the formula to find out the area of a circle i.e. πr²
- Divided the area by half as the disc was semicircular .
