The answer is the transitive property
Circumference = 43.96 cm, find radius:
Circumference = 2πr
43.96 = 2(3.14)r
43.96 = 6.28r
r = 43.96 ÷ 6.28 = 7 cm
We found out that the radius is 7 cm, find surface area:
Surface area = 4πr² = 4 (3.14) (7)² = 615.4 cm² (nearest tenth)
Answer: 615.4 cm²
Answer:
8√2
Step-by-step explanation:
This is a 45-45-90 right triangle with a Pythagorean triple of (x, x, x√2). Because this is a 45-45-90, both legs have the same measure, namely 8. Therefore, according to the Pythagorean triple, x = 8 (NOT the x in your diagram...the x in the Pythagorean triple). That means that the hypotenuse has a measure of 8\sqrt{2}8
2
, which is d.
