Answer:
20.57 cm
Step-by-step explanation:
Circumference of half circle = diameter + half of circumference
150 + 30 = 180, right? We need to find 180 on the other side.
180 - 2 = 178
178 / 4 = 44.5
The answer is most likely 44.5. Let me know if I am wrong,
Area of rectangle: 7 x 10 = 70 in2
Area of semicircle: (r^2*π)/2 = 3.5^2 * π /2 = 6.125*<span>π
</span>
=> Total area = 70 + 6.125*<span>π = 70 + approx 19.24 = approx. 89.24 in2</span>
------------------------------------------------------------------------------------------------------
The closest number here is 89 in2, so the answer is 89 in2.
