Answer:
8√π/π
Step-by-step explanation:
A = 64 = π·r²
r² = 64/π
= √64/√π
= 8/√π
= 8√π/π

3) Neither
4) Neither
Step-by-step explanation:
Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.
Step-by-step explanation:
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.
Answer:
B. 17
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
7 (7 + x) = 8 (13 + 8)
49 +7x = 8*21
7x = 168 - 49
7x = 119
x = 119/7
x = 17
If the width is 8ft and the length is twice the width then multiply 8 by 2 to find your length
