Answer:
3² + 6 × 2² - 4² ÷ 2³ = 31.
Step-by-step explanation:
Circumference of the wheel = pi*d = 26pi ins = 13pi / 6 feet
there are 8280 feet in 1 mile
The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs
13 pi
a) Rectangles always have 4 right angles (90 degrees), but parallelograms do not always have 4 right angles rather they can, but do not have to. Rectangles have to.
b) A square is a type of rectangle, but a rectangle is not a type of square. Both rectangles & squares have 4 right angles and are always quadrilaterals, but squares always have all sides that have the same length, but rectangles do not have to have their sides all equivalent lengths.
c) In the case of a parallelogram, the opposite sides are equal whereas in a rhombus all four sides are equal.
Answer:
40 ft²
Step-by-step explanation:
Divide the figure into 2 rectangles and find their areas.
The area of the smaller rectangle
= 3 × 4
= 12 ft²
The area of the larger rectangle
= (8-4) × 7
= 28 ft²
The area of the figure
= 12 + 28
= <u>40 ft²</u>
