Answer:
The coaster’s radius is 5 cm
Step-by-step explanation:
Drink Coaster has a circular shape.
Area of a circle = π*r²
so, area of the drink coaster = π x (Radius of the drink coaster)²
Given that Area of the drink coaster is 78.5 cm²
∴ 78.5 cm² = π*r²
Also we are to use 3.14 for π
∴ 78.5 cm² = 3.14*r²
r² = 78.5 cm² / 3.14
r² = 25 cm²
r = cm
r = 5 cm
Hence, the coaster’s radius is 5 cm
