What is area of s circle with 1 inch radius?
The area of Circle S can be found by using the area formula for circles. The area of a circle is pi times the radius squared. So, the area of Circle S with a 1 inch radius is Pi inches squared.
What is the surface area of a cylinder with end that are half sphere with a radius of 4 and height of 12?
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
What is the radius of a circle when the area is 96?
The radius of a circle when the area is 96 is 5.528
Square mile to mile radius?
A circle with a mile radius has an area of pi sq miles.
How many acres in a 5 mile radius?
A circular area of 5 miles radius covers 50265.5 acres(to 1 dp) Area = pi*radius2, which with radius in miles will give you area as 78.53982 square miles, then multiply by 640, since there are 640 acres in 1 square mile.
The area to an 80 mile radius?
The area of a circle is: pi times radius^2
What is a radius mile?
anything around the area.
What is the area growth from 3 mile radius to a 15 mile radius?
Area variesa s pi times the radius squared. 15/3 = 5; 5 squared = 25 A radius of 15 miles grows the area 25 times
Is 40 mile radius the same as 40 miles?
No, 40 mile radius is an area unit whereas 40 mile is distance. This means that something 30 miles from a location can be said to be in a 40 mile radius from that location.
How many square miles in a 50 mile radius?
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
What is the radius of a 1 mile circle?
The radius is (Circumference/pi)/2. In this case it is (1 mile/pi)/2 Note: pi = 3.1415926535...
How many square miles in a 40 mile radius?
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
How many acres in a 1 mile radius circle?
Use the formula for the area of a circle: area = pi x radius2. Then convert square miles to acres.
A radio broadcast can be heard within a 50-mile radius. What is the approximate area the radio broadcast can be heard?
A radio broadcast can be heard within a 50-mile radius. What is the approximate area the radio broadcast can be heard?
An fm radio station signal travels in a 40 mile radius an am radio station signal travels in a 4 mile radius how much more area does the fm station cover than the am station?
You're talking about circular areas.-- The area of a circle is (pi) x (radius)2 .-- The area of the 4-mile radius is (pi) x (4)2 = 16 pi square miles-- The area of a circle is proportional to the square of its radius.So the area of the 40-mile radius is (10)2 = 100 times the area ofthe 4-mile radius = 1,600 pi square miles.The larger circle has (99 times the area of the 4-mile radius) more areathan the smaller circle has.(99) x (16 pi) = 1,584 pi = 4,976.3 square miles more than the smaller circle.
