Answer:I like the view
Step-by-step explanation:
Answer:
by simply multiplying these 2 dimensions.
9.1 ft²
Step-by-step explanation:
2 4/5 × 3 1/4 = (14/5) × (13/4) = (14×13) / (5×4) =
= (7×13) / (5×2) = 91/10 = 9.1 ft²
Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
Answer:
Area of the rectangle is 10x²+7-6
Step-by-step explanation:
Area of rectangle is the product of its length and width
As length of given rectangle is 5x+6 and its width is 2x-3 the are is
(5x+3)(2x-3)
=5x·2x-5x+6·2x-6
=10x²-5x+12x-6
=10x²+7x-6
Answer:
1256000
Step-by-step explanation:
My example:
Find the radius of the sphere by substituting 4.5? ft^3 for V in the formula in Step 1 to get: V=4.5? cubic feet.= (4/3)?(r^3)
Multiply each side of the equation by 3 and the equation becomes: 13.5 ? cubic feet =4?(r^3)
Divide both sides of the equation by 4? in Step 4 to solve for the radius of the sphere. To get: (13.5? cubic feet)/(4?) =(4? )(r^3)/ (4?), which then becomes: 3.38 cubic feet= (r^3)
Use the calculator to find the cubic root of 3.38 and subsequently the value of the radius “r” in feet. Find the function key designated for cubic roots, press this key and then enter the value 3.38. You find that the radius is 1.50 ft. You can also use an online calculator for this calculation (see the Resources).
Substitute 1.50 ft. in the formula for SA= 4?(r^2) found in Step 1. To find: SA = 4?(1.50^2) = 4?(1.50X1.50) is equal to 9? square ft.
Substituting the value for pi= ?= 3.14 in the answer 9? square ft., you find that the surface area is 28.26 square ft. To solve these types of problems, you need to know the formulas for both surface area and volume.
