Answer:
Step-by-step explanation:
sides of triangle are (4+3) and (2+3)
or 7,5
area of triangle=1/2×7×5=35/2=17.5 cm²
area of rectangle=3×2=6 cm²
area of shaded region=17.5-6=11.5 cm²
Answer:
28.26 
Step-by-step explanation:
The radius is half of the diameter. 6/2 = 3, so the radius of this circle is 3 cm.
The formula for the area of a circle is: π
Plugging 3 into the radius, we have:
× π =
9 × π
We can round π to 3.14
9 × 3.14 = 28.26
