How do I draw a Shape 1metre in length, in my homework book? A regular shape that big will not fit in my homework book, so I need an irregular shape ideas.

While finding a measure of an angle, what do I do if one of the angles inside of the triangle does not have a number but the outside angle does?

One person walked to 'B', a distance of 21m from 'A'. He then rounded the circle with 'A' as the focal point and returned again to 'A'. So how many total runs did I do?

A square piece of material with sides 150 cm is used to make a circular table cloth. The diameter of
the completed cloth must be 1,2 m and 5 cm is provided for a hem. How much material is wasted?
(Answer correct to 2 decimal places.)
1. 1,30 m2
2. 92,26 cm2
3. 0,92 m2
4. 129,97 cm2

Which of the following statements is/are true?
A. Suppose a sphere has a diameter of 10 cm. Suppose the height of a closed right circular cylinder
is double its radius, and that its radius is the same as the radius of the sphere. The ratio of the
surface area of the sphere to that of the cylinder is 2 : 3.
B. If the diameter and height of a right circular cone are equal then the lateral surface area of the
cone is √
5πr2
, where the radius is r. (Note: Lateral surface area of cone is the area of the sides
only.)
C. If the diagonals of a quadrilateral intersect at right angles the quadrilateral must be a square or
a rhombus or a kite.
1. Only A 2. Only B 3. Only C
4. Only A and C 5. A, B and C

If sec α = 5/4 and cot β = 3/4, α is acute, and 1800 < β < 2700. Then, cos (α + 2β)

one side of a parallelogram is 10'' long and make angles 45° and 75° with the diagonals. find the length of the other side

A rhombus has diagonals of 32 and 20 inches. Find the angle of opposite the longer diagonal

True /false
1.A spehere has radius 3a units.Right circula cylinder has a height 4times its radius which is a units.The ratio of the volume of the cylinder to the sphere is 1:9
2.Consider a circle with diameter d units and a square with diagonal d units.If a fly crawls round the circle once and an ant crawls round the square once , the fly travels further.
3.Volume of a right circular cone with height 15cm is the same as the volume of a right circulat cylinder with height 5cm, if the both have the same radius

b.( -1,9/4)
c. (9/2, -1)
d. (9/2, 9/2)
