## What is the area of the sector that is not shaded? 12 units 24 units? 120 units 144 units IM ON A TIME LIMIT HURRY!!

Hey there! And welcome to Brainly.

Remember that the area of a circle is π*radius^2Remember that there are 360° in a circle.

The angle of the unshaded part would be 360° minus the shaded part of 60°.360°- 60° = 300°Since the area of a circle is πr^2, and the section of the circle is 300°, or 300/360 = 5/6 or one full circle, the area of the unshaded region is(5/6)π*radius^2= (5/6)π*12^2= 120π units^2

How to find the area of a sector – SAT Math – The area of the semi-circle is half the area of a circle with radius 5. The area of the full circle is 5 2 π = 25π, so the area of the semi-circle is half of that, or 12.5π. The total area of the plot is the square less the semicircle: 900 – 12.5π square feet. The cost of upkeep is therefore 2.5 * (900 – 12.5π) = $(2250 – 31.25π).Question 4: Find the area of a sector with an arc length of 40 cm and a radius of 12 cm. Module Five Lesson Three Block Two You Try Question 1: The length of arc AB is 5π units and the measure of ∠ACB is π/6. Find the length of the radius. Question 2: The diameter of DB is 24 cm. Find the length of arc AB given the picture below.This free area calculator determines the area of a number of common shapes using both metric units and US customary units of length, including rectangle, triangle, trapezoid, circle, sector, ellipse, and parallelogram. Also, explore the surface area or volume calculators, as well as hundreds of other math, finance, fitness, and health calculators.

Question 3 Find the area of the shaded sector if BCA 120 – Area of sector. In a circle with radius r and center at O, let ∠POQ = θ (in degrees) be the angle of the sector. Then, the area of a sector of circle formula is calculated using the unitary method. When angle of the sector is 360°, area of the sector i.e. the whole circle = \(πr^2\) When the angle is 1°, area of sector = \(\frac{πr^2120 cm 2. 180 cm 2. Tags: Question 11 . SURVEY . 900 seconds Q. Find the area of the shaded sector of circle O. The radius is 6 inches and the central angle is 100°. When she is outdoors, Tasha, the dog, is tied to a stake in the center of a circular area of radius 24 feet. The angle between her dog house and her favorite hydrant isTherefore the shaded area would have a smaller area than with the hexagon. What is the area of a sector with measure of arc equal to 90° and radius equal to 1 foot? 0.5(PI) sq. ft.

Area Calculator – The circumference of a circle is the linear distance around the circle, or the length of the circle if it were opened up and turned into a straight line.. The area of a circle is the number of square units it takes to fill up the inside of the circle.. Note the circumference and area apply to the entire circle.. In the case of arc length and sector area, you will only be dealing with a portionDetermine the radius if the central angle is 120 degrees and the shaded region has an area of 75 π. 75π = 120/360 * πr 2 75 = 1/3 * r 2 3/1 (75) = 3/1 (1/3 * r 2) 225 = r 2 r = 15 Determine the measure of the central angle if the radius is 12 and the area of the sector is 108 π.The area of the circle is 25 pi, so the area of the semicircle is 12.5 pi. Therefore the area of the shaded region is 12.5pi-25. 0 0. kathycat10. 1 decade ago. for the first one: according that it is a circle AND NOT a sphere: diameter=10cm. radius=5cm. first of all you find the area of the whole circle.
