Answer:
(x +8)² +(y +6)² = 100
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r can be written:
(x -h)² +(y -k)² = r²
For your given values of h=-8, k=-6, r=10, the equation is ...
(x +8)² +(y +6)² = 100
Answer:
201.1 km²
Step-by-step explanation:
Surface area of the figure,
4πr²
= 4×π×4²
= 64π
= 201.1 km² (rounded to the nearest tenth)
Answer:
y = 4
Step-by-step explanation:
Since the 2 rectangles have the same area, then
12.5 × 2y = 5 × 20
25y = 100 ( divide both sides by 25 )
y = 4
