Find the area of the shaded region of the composite figure below. Use 3.14 for pi. a 7.74 in2 b 77.04 in2 c 64.26 in2 d 28.26 in2

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
