Weegy: Area of triangle = 1/2 x base x height =1/2 x 6 x 8 = 24 square metre. User: What's the proper name of the quadrilateral below? Weegy: 2 + 2 = 4 User: The area of a square piece of cardboard is 81 square inches. What is the length of the cardboard? Weegy: The area of a square piece of cardboard is 81 square inches, therefore the length of the cardboard is 9 inches. Square root of 81=9 User: A cylindrical tank has a radius of 15 feet and a height of 45 feet. How many cubic feet of water can the tank hold? Weegy: A cylindrical tank has a radius of 15 feet and a height of 45 feet. The tank can hold 31,792.5 cu. ft. of water. Sol'n: V = pi * r^2 * h; v = 3.14 * (15^2) * 45 V = 3.14 * 225 * 45; V = 31,792.5 User: Find the circumference of a circle if the area is 300 square centimeters Weegy: The circumference of a circle if the area is 300 square centimeters. Area = pi*r^2 = 3.14*r^2 , area = 300 , r^2 = 300/3.14 = 95.5414 , r = 9.77cm , circumference =2 *pi*r =2*3.14*9.77 = 61.38 cm. User: If the area of a square is 64 square centimeters, what's the length of one side? Weegy: If the area of a square is 64 square centimeters, the length of one side is 8 cm. Solution: A = s^2 s = square root of 64 cm s = 8 cm. User: What's the area of an equilateral triangle with sides of 10 inches and height of 7 inches? Weegy: 2 + 2 = 4 (More)

Weegy: 2 + 2 = 4 User: If the area of a circle is 58 square feet, find the circumference. Weegy: If the area of a circle is 58 square feet, the circumference is 26.99 ft. Solution: Solving for r: Area = pi * r^2 58 = 3.14 * r^2 r^2 = 58/3.14 =18.47 r = 4.29 Circumference = 2 * pi * r Circumference = 2 * 3.14 * 4.29 = 26.99 ft. User: Which type of triangle has one angle with a measurement greater than 90? Weegy: Obtuse type of triangle has one angle with a measurement greater than 90 . User: What's the length of side b in the figure below? Weegy: 1+1=2 User: What's the volume of a cube=shaped box with edges 6 centimeters in length? Weegy: The volume of a cube-shaped box with edges 6 centimeters in length is: 6 x 6 x 6 = 216 cm . Solution: V = s*s*s; V = 6 * 6 * 6 = 216 cm? User: An earthquake was felt throughout a circular area of 1,808.64 miles. What was the radius of the circular area? Weegy: An earthquake was felt throughout a circular area of 1,808.64 square miles. The radius of the circular area is 24 miles. 1,808.64 sq. mi. So, (pi)(r^2) = 1,808.64 Solve for r. [ Divide both sides by pi (3.14) r^2 = 1.808.64/3.14 r^2 = 576 Take the square root of both sides. r = 24 Miles. ] User: A triangle with all sides of equal length is a/an _____ triangle Weegy: A triangle with all sides of equal length is an equilateral triangle. User: What is the radius of a circle with an area of 32.1 square feet? Weegy: The radius of a circle with an area of 32.1 square feet is 3.20 ft. .Area = pi*r^2 , Area = 32.1 , Area = 3.14*r^2 , 32.1 = 3.14*r^2 , r^2 = 32.1 /3.14 = 10.22 , r = 3.20 ft. User: If a triangle has a height of 14 inches and a base of 9 inches, what's its area? Weegy: 2 + 2 = 4 (More)
