Question

I need help with number 2, thanks!

Answer 1

Answer:

259.97

Step-by-step explanation:

To calculate the area, use the area formulas for a triangle and half a circle.

The area of a triangle is A = b*h where h is a perpendicular height. Here h = 10 and b = 14. So the area is A = 1/2*14*10 = 70.

The area of half a circle is A = 1/2 πr². Here r = 11 or half the diameter which is 22. 22/2 = 11. So the area is A = 1/2π(11)² = 1/2π(121) = 189.97.

Together the area is 70 + 189.97 = 259.97.
