Okay,
We see that there are to shapes- semi circle and trapezoid
Area of the semicircle:
1/2πr^2
r=4.5 cm
A≈31.8 square cm.

Area of the trapezoid=1/2(b1+b2)h
h=2r
h=9cm
b1=9.5cm
b2=12 cm
A=96.75 square cm
A=96.75+31.8
A≈128.55 square cm is your final answer. Hope it help!

vekshin1

Answer:

70 times

Step-by-step explanation:

5 consecutive even integers: 2n, 2n+2, 2n+4, 2n+6, 2n+8 for any integer n The sum of the two smallest of five consecutive even integers is 50 less than the sum of the other three integers: 2n + 2n+2 = 2n+4 + 2n+6 + 2n+8 - 504n + 2 = 6n -3234 = 2nn = 17 The smallest integer in our sequence is 2n = 2*17 = 34 Check:2n + 2n+2 = 2n+4 + 2n+6 + 2n+8 - 5034 + 36 = 38 + 40 + 42 - 5070 = 120 - 5070 = 70
