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.

If y varies inversely as x and y=2 when x =25 find x when y=40.
Ghella [55]
Ok, since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25!!!!! :)
