The radiusof <span> (x^2−6x)+(y^2−10y)=−18 </span>is 4
Answer:-250
Step-by-step explanation:
3/5 miles = 0.6 miles
0.6/4= 0.15 miles
Nikki walked 0.15 miles or 3/20 miles.
Multiply the bottom of the fractions together (4*5=20) and the tops (3*1=3) to get 3/20.
S = πr(r + √(h² + r²))
400.2 = 3.14(6)(6 + √(h² + 6²))
400.2 = 18.84(6 + √(h² + 36))
18.84 18.84
21¹⁰⁹/₄₇₁ = 6 + √(h² + 36))
- 6 - 6
15¹⁰⁹/₄₇₁ = √(h² + 36)
231²²¹⁰⁰⁵/₂₂₁₈₄₁ = h² + 36
- 36 - 36
195²²¹⁰⁰⁵/₂₂₁₈₄₁ = h²
14 ≈ h
6=5/2(6)+b
6=15+b
subtract 15 from both sides
b=-9
