Answer:
Calculate the square root of 10 ( ) to 2 decimal places.
Find the two perfect square numbers it lies between. Solution: 32 = 9 and 42 = 16, so lies between 3 and 4.
Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.

Answer:
The value of BK is 3m and the value of CK is 2.4m.
Step-by-step explanation:
Given information: ABCD trapezoid
, BC=1.2m, AD=1.8m
, AB=1.5m, CD=1.2m
, AB∩CD=K.
Using the given information draw a figure.
Two sides of a trapezoid are parallel.
Since AB∩CD=K, therefore AB and CD are not parallel, because parallel line never intersect.
(Corresponding angles)
(Corresponding angles)
By AA rule of similarity
Corresponding sides of similar triangles are proportional.
The length of BK is 3 m.
The length of CK is 2.4 m.
Answer:
220
Step-by-step explanation:
The surface area is given by
SA = 2 ( lw+wh+lh) where l is length h is height and w is width
SA = 2(3*4 + 3*14+ 4*14)
= 2(12+42+56)
= 2(110)
= 220
Answer: C
Step-by-step explanation:
When you are finding the area, the formula is A= Pi R^2.
The radius is half of the diameter. To get a diameter of 6, you have to multiply 3 by 2.
