Answer: t = 11/2
Step-by-step explanation:
V=LWH, W=L-3, H=5, V=270
L(L-3)5=270
5L^2-15L=270
5L^2-15L-270=0
L^2-3L-54=0
L^2+6L-9L-54=0
L(L+6)-9(L-6)=0
(L-9)(L+6)=0
Since L>0
L=9 meters
Answer:
Step-by-step explanation:
<u>Area of circle:</u>
<u>Distance between x and y is same as r, so:</u>
- r² = (0 + 3)² + (3 + 1)² = 9 + 16 = 25
<u>Then the area is:</u>
- A = π*25 = 78.5 units² (rounded)
