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).
How can you calculate the radius with the area given to you?
Area of a circle = pi x radius squared, so to get the radius, divide the Area by pi (3.14159), and then find the square root of that
How many acres are in a 1 mile radius?
To calculate the number of acres in a 1-mile radius, we first need to find the area of a circle with a radius of 1 mile. The formula to calculate the area of a circle is A = πr^2, where r is the radius. So, the area of a circle with a 1-mile radius would be A = π(1)^2 = π square miles. To convert this area to acres, we need to know that 1 acre is equal to 43,560 square feet. Since there are 640 acres in a square mile, the number of acres in a 1-mile radius circle would be approximately 640π acres.
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
How many acres in a 1 mile radius circle?
A 1 mile radius circle covers approximately 3.14 square miles, which is equivalent to 2,008 acres.
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 6 mile radius?
The area of a circle with a 6-mile radius is approximately 113 square miles.
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 25 mile radius?
The area of a circle with a 25-mile radius is about 1963.5 square miles. This calculation is based on the formula A = πr^2, where A is the area, π is approximately 3.14159, and r is the radius of the circle.
