Answer:
Solution given:
r=3km
area of sector bounded by a 90° arc=90°/360°*πr²
=¼*π*3²
=<u>9/4 π or 7.068km²</u>
is a required answer
Answer:
<u>it is 0.4</u>
Step-by-step explanation:
To answer this, we need to see the polynomial. Descending order is in a way that the first term of the polynomial will be three, the second (in descending order, two....and so on).
420t+20t3-210t2
In descending order is:
20t^3 - 210t^2 + 420t
So, the option is number two.
Answer:
26
Step-by-step explanation:
Because You have to just do the perimeter by counting the sides
Answer:
105
Step-by-step explanation:
It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
(91+89+X)/3 =95
91+89+X =95*3
180+X =285
X =285 - 180
=105
