$<span>1,241 is my answer. I used a calculator for interest, so I'm sure this is the correct answer. Rounding it to the nearest hundredth I suppose it would be $1,200. I'm not good at rounding, but I hope this has helped you some.</span>
Area of triangle ABC can be found using the formula ¹/₂ × b × c × sin (A)
Substitute b = 9, c = 7, and m∠A = 66° into the formula gives
Area = 9 × 7 × sin 66° = 57.55
ANSWER: D
Answer:
Correct answer: C. 936π ft³
Step-by-step explanation:
The formula for the volume of a sphere is:
V = 4/3 r³ π
Let the radius of the first sphere be r₁ = 3 ft and the second r₂ = 9 ft
Increasing the volume of the sphere is equals to the difference of V₂ and V₁
ΔV = V₂ - V₁ = 4/3 r₂³ π - 4/3 r₁³ π = 4/3 π ( r₂³ - r₁³ ) = 4/3 π ( 9³ - 3³ )
ΔV = 4/3 π ( 729 - 27 ) = 4/3 π · 702 = 4 · 234 · π = 936 π ft³
ΔV = 936 π ft³
