Answer:

Cost to pave the road = $4257

Step-by-step explanation:

Area of the pavement = Area of the outer circle - Area of the internal circle

Area of the outer circle = πr²

= π(55)²

= 3025π square feet

Area of the inner circle = π(33)²

= 1089π square feet

Area of the pavement = 3025π - 1089π

= 1936π

= 6082.12 square feet

Cost of pavement = $0.70 per square feet

Therefore, cost of 6082.12 square feet = 6082.12 × 0.70

= 4257.49

≈ $4257

Cost to pave the road = $4257

HEy, CAn YOu HElp ? :) Plssss (picture below) solve for #5

alexira [117]

Answer: a=60°, b=25°, c=95°,d=60°, e=25°, f=95°, g=60, h=35°

Step-by-step explanation:

a=60°, Because the angle opposite to it is 60°

b=25°, Because if you take 180°-155°, you get 25°

c=95°, Because if you add angles a and b, you get 85°, then you do 180°-85°=95°

d=60°, Because the angle opposite to it does

f=95°, Because angle c, which is opposite to it equals 95°

g=60°, Because if you add angles e and f, you get 85°, then you take 180°-85=95°

h=35°, Because if you add angles c and d, which is 155°, you take 180°-155=35°

Solve for x. Assume that lines which appear tangent are tangent.

NeX [460]

Answer:

x=2

Step-by-step explanation:

The angle formed by two tangents intersecting outside of a circle is half the difference of the intercepted arcs.

This implies that:

$55=\frac{1}{2}(116x+3-(180-55))$

We need to simplify this ad solve for x to get:

$110=(116x+3-125)$

Group the similar terms to get:

$110-3+125=116x$

232=116x

Divide by 116 to get:

x=2
