Number 7 i can not figure out for anything. i keep getting the answer of 103.1 but the back of the book says its 88.1 ft squared. can someone show me how to get this answer?

You have a semicircle attached to a trapezium

Area of semicircle = 1/2 Pi r^2 = 1/2 + pi * 4^2 = 25.13 ( note r = 1/2 * 8 = 4)

Area of the trapezium = h/2 ( sum of 2 parallel sides) = 1/2 * 6 * (13 + 8)

= 63

Total area = 63 + 25.13 = 88.1 to nearest tenth

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
