Answer:
6.25π cm²
Step-by-step explanation:
pi = π
Circumference = 5πcm
Now first we should find radius(r)
2πr = 5π cm
pie will be cancelled and we get here
r = 5/ 2 cm
Therefore r = 2.5 cm
Now
Area (A) = πr²
= π * 2.5²
= 6.25π cm²
Answer:
672 sq cm
Step-by-step explanation:
Each triangular base is 1/2 (12 * 8) or 48, making them = 96.
