Answer:
Step-by-step explanation:
<u>Work:</u>
- 2(π x 21 x 21/2) + (π x 42 x 42/4) = Area of figure
- => π x 21 x 21 + (π x 42 x 42/4) = Area of figure
- => (22/7 x 21 x 21) + (22/7 x 21 x 21) = Area of figure
- => 2(22/7 x 21 x 21)
- => 2(22 x 3 x 21)
- => 2772 cm²
Hence, the area of the shape is 2772 cm².
Answer:
It's 3/2p!
Step-by-step explanation:
Because Helen do the same number of exercises on 2 days, the time to do and the average rate are inversely proportional!
