Answer:
225π ft²
Step-by-step explanation:
The area of the circle is given by the formula ...
A = πr²
The figure shows the radius (r) is 15 ft. Using that value, we find the area to be ...
A = π(15 ft)²
A = 225π ft² . . . . exact area of the circle
Answer:
68
Step-by-step explanation:
Use the formula provided...
6 and 11 are b1 and b2, and 8 is h.
So, 6+11 = 17
17/2 = 8.5
8.5*8 = 68

Answer:
105 cm²
Step-by-step explanation:
The figure is composed of a rectangle and a triangle
area of rectangle = 15 × 6 = 90 cm²
area of triangle =
bh ( b is the base and h the height )
Here b = 15 - 9 = 6 and h = 11 - 6 = 5 , thus
area of triangle =
× 6 × 5 = 3 × 5 = 15 cm²
Total area = 90 + 15 = 105 cm²
