Find the perimeter of this semi-circle with diameter,

Mathematics
1 answer:
KATRIN_1 [288]1 year ago
6 0

The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle with diameter of 38 cm.

Diameter = 38 cm

The radius of the circle = 38/2 = 19 cm

Perimeter of the circle = 2πr = 2π(19) = 38π cm

Perimeter of the semicircle = 38π/2 = 19π cm

Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

A volcano on a recently discovered planet rises to a height of 16.871 mi.
Vinvika [58]
The answer is 89078.88 ft

1 mile = 5280 feet

Multiply 16.871 by the length value of 5280

16.871 * 5280 = 89078.88 ft

What constant acceleration is needed to accelerate a baseball from 6 feet/sec to 116 feet/sec in 2 seconds?
Vesnalui [34]

Answer:

  d. 55 feet /sec^2

Step-by-step explanation:

Average acceleration is ...

  a = ∆v/∆t = (116 ft/s -6 ft/s)/(2 s)

  = 110/2 ft/s^2 = 55 ft/s^2

How do i solve for this?
Firdavs [7]

9514 1404 393

Answer:

  97.42 square units

Step-by-step explanation:

The area of a sector is given by ...

  A = (1/2)r²θ

where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.

  75° = (75°)×(π/180°) radians = (5/12)π radians

Then the area is ...

  A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units

__

Equivalently, you can find the area of the circle in the usual way:

  A = πr² = π(12.2²) ≈ 467.59465

Then, multiply by the fraction of the circle that is shaded (75°/360°)

  sector area = (467.59465)(75/360) = 94.42 . . . square units
