Formula for surface area is pi DH.diameter is radius multiplied by 2 which is 2.8.pi is22/7.multiply 22/7 to 2.8 which is 8.8.multiply 8.8 with height(5 inches) to get 44.0 as the answer
Answer:
112
Step-by-step explanation:
This is a cyclic quadralterial. A cyclic quadralterial is a quadralterial that is inscribed in a circle where all the point or vertices of the quadralterial touches the circle circumference. Opposite angles in a cyclic quadralterial are supplementary.
Angle R and Angle QPS or P is supplementary since they are opposite angle.
Substitute 68 for R
So the answer is 112
Answer:
21.25
Step-by-step explanation:
85/4 = 80/4+5/4 = 20 + 1 + 1/4 = 21 + 0.25 = 21.25
The height of a tree is 10
10
meters long and it grows 1
1
cm in a year.
Then its height after one year = 10
10
meters 1
1
cm
Its height after 3
3
years = 10
10
meters 3
3
cm
Its height after 6
6
years = 10
10
meters 6
6
cm
Its height after x
x
years = 10
10
meters x
x
cm
Where x
x
represents an unknown number. From the last line, we can find height of the tree after a certain number of years by taking x
x
equal to that number. For example, we simply let x=15
x
=
15
, 25
25
and 55
55
. Thus, the value of x
x
depends on our choice. We can give x
x
any value or number we want. In other words, the value of x
x
is not fixed, it varies from one situation to the other. Therefore, we call x
x
a variable whereas 10
10
is a fixed number whole value does not change. So 10
10
therefore is called a constant.
