Answer:
1.6in
Step-by-step explanation:
We could find the length of the radius of the small circle using pythagorean theorem. There is a right triangle formed from the picture above. Pythagorean theorem states the sum of the squares of the perpendicular sides on the right triangle is equal to the square of its hypotenuse.
(8 - r)² + 20² = 21²
(8 - r)² + 400 = 441
(8 - r)² = 441 - 400
(8 - r)² = 41
8 - r = √41
r = 8 - √41
r = 8 - 6.403
r = 1.597
to the nearest tenth
r ≈ 1.6
Answer:
32
Step-by-step explanation:
first angle is 20, let third angle be x, therefore second angle equals 4x; angle in a triangle is 180, so 4x+x+20=180; 5x=160; x=32
The radius will equal half of the length of a side of the square.
The length of the side for this square lawn = √200 so the radius will be 1/2 * √200.
Answer 7.07 feet (to nearest hundredth.
2*2*2*x=28. 8x=28. x=28/8
Answer:
-1000
Step-by-step explanation:
-10 times -10 makes 100 as negative cancel each other
100 times -10 make -1000
