Answer:
48.5cm²
Step-by-step explanation:
The figure is can be divided into 3 parts:
The square, The rectangle and The triangle
We will be finding the area of each shape.
The square: Area = length * length
Length of square = 3. Area = 3 cm * 3 cm = 9 cm²
The rectangle: Area = length * breadth
Length = 8 cm; Breadth = 4 cm. Area = 8 cm * 4 cm = 32 cm²
The triangle: Area = 0.5 * height * base
Height = 5 cm; Base = 3 cm. Area = 0.5 * 5 * 3 = 7.5 cm²
Base is the shorter side of the triangle that is not the diagonal side (hypotenuse). It is gotten by subtracting the given length of the bottom part of the figure which is 4 cm from the top part of the figure which is 7 cm and it is also the other side of the square that is not given.
Height is the longer side of the triangle that is not the hypotenuse.
It is gotten by subtracting the given length of the right side which is 3 cm from the given length of the left side of the figure which is 8 cm.
Base and height can be used interchangeably.
Adding all the areas together: 9 + 32 + 7.5 = 48.5 cm²
Answer:
The difference can be elaborated by the following equation
"4 times the sum of x and y" ![=4(x+y)](https://tex.z-dn.net/?f=%3D4%28x%2By%29)
and "sum of 4 times x and y" ![=4x+y](https://tex.z-dn.net/?f=%3D4x%2By)
Step-by-step explanation:
In the first condition the two terms x and y are summed up first then multiplied by 4. First add two digits then multiplexed..
In second case the 4 times of x is first calculated then added with y.
Note:
First condition will always be greater than second because in first condition both the digits are multiplied with 4 but in second only second is multiplied with 4.
Answer:
Step-by-step explanation:
Hello there, to answer this question, one must know the formula of area of a circle.
1. Use formula for area of circle to find area of base of cylinder
2. Multiple area of base with height of cylinder for volumne
Area = pi * r * r
Cylinder A:
Area: pi * 6 * 6 = 113.1 inches square
Volumne = Area * Height = 113.1 * 4 = 452.4 inches cube
Cylinder B:
Area: pi * 5 * 5 = 78.54 inches square
Volumne = Area * Height = 78.54 * 5 = 392.7 inches cube
Cylinder C:
Area: pi * 4 * 4 = 50.27 inches square
Volumne = Area * Height = 50.27 * 6 = 301.62 inches cube
31/36 is the correct answer
Answer:
q(2)=20
Step-by-step explanation:
Substitute the 2 into the 10m, which will be 10(2). Then, multiply those two numbers, and you'll get 20
