Answer:
the base is 10 and the height is 6.4
Answer:
≈ 62.8
Step-by-step explanation:
Using the equal ratios of
=
, that is
=
= 5, thus
5 × sector = 100π ( divide both sides by 5 )
sector = 20π = 20 × 3.14 = 62.8 units²
When you plug in the numbers for the integers, you get
8.2-2(-3.7)
If you multiply -2 and -3.7, you get 7.4 because the negatives cancel each other out.
If you then add 8.2, you get 15.6. So the answer is D.
