Answer 1

C and E

Explanation:

7.2 - 2.8 = 4.4

10 - 6 = 4 x 4.4 = 17.6/2 since it is a triangl3 is 8.8 that is the area of the missing corner.

10 x 7.2 = 72 - 8.8 = 63.2 so C.

Formula for a circle is r x r x 3.14 so 8 x 8 = 64 x 3.14 = 200.96

16 x 12 = 192 / 2 since it is a triangle is 96 + 200.96 = 296.96 so E since the pi might have been extended to more digits.
