The length (L) of the figure is 11 mm and the width (w) is 9 mm. What is the perimeter of the shaded region? Round to the neares
Lera25 [3.4K]

Answer:

50.3 mm

Step-by-step explanation:

The perimeter of the shaded region = perimeter of a full circle + 2(Length)

= πd + 2(L)

diameter (d) = width = 9 mm

Length (L) = 11 mm

Perimeter of the shaded region = π*9 + 2(11)

= 50.2743339 ≈ 50.3 mm (nearest tenth)

How far up the house would a ladder be resting if it is 25 ft long and 3 ft
Lena [83]

Answer:

C

Step-by-step explanation:

The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.

Givens

a = 3

b = ?

c = 25 feet

Formula

a^2 + b^2 = c^2

Solution

3^2 + b^2 = 25^2

9 + b^2 = 625                  Subtract 9 from both sides.

b^2 = 625 - 9

b^2 = 616                        Take the square root of both sides.

b = sqrt(616)

b = 24.8
