Answer:
C
Step-by-step explanation:
Using the sine ratio and the exact value sin45° =
, then
sin45° =
=
=
( cross- multiply )
a = 6
Using the tangent ratio and the exact value tan45° = 1 , then
tan45° =
=
= 1 , so
b = 6
The town will spend $202.5 on laying the pipes.
Step-by-step explanation:
Given points are;
(-2,-4) and (6,-5)

Distance of two points is;

As one unit represent a mile, therefore,
Distance = 8.1 miles
Cost of laying 1 mile = $25
Cost of laying 8.1 miles = 8.1*25 = $202.5
The town will spend $202.5 on laying the pipes.

Answer:
Step-by-step explanation:
A = π r²
A = 11²π - 3²π = ( 121 - 9 ) π = 112 π ≈ 112 ×
= 352 cm²
( 112 × 3.14 = 351.68 cm²)
