step-by-step explanation: 1/2 (a+b) x h is area of trapezoid. So that would be 40 then area of circle is pi x radius squared. So that is 50.24 roughly.
M = - 1/5 y = m x + b 7 = - 1/5 · ( - 3 ) + b 7 = 3/5 + b b = 7 - 3/5 b = 35/5 - 3/5 b = 32/5 The equation is: y = - 1/5 x + 32/5 or : y = - 0.2x + 6.4
