Answer:
113.04 cm³
Step-by-step explanation:
diameter = 6cm
so radius = 3cm
Volume of sphere = 

= 4 * 3.14 * 3 * 3 *3 / 3
= 4 * 28.26
= 113.04 cm³
Answer:
(2.5,3.5) ywww
Step-by-step explanation:
Answer:
3.5
Step-by-step explanation:
First we use the concept of relative speed.
The rates of the 2 planes are 625 mph & 575 mph.
Relative speed will be:
(speed of plane A)+(speed of plane B)
=625+575
=1,200 mph
Distance=4200 miles
Thus the time taken for them to meet will be:
Time=distance/speed
=4200/1200
=3.5 hours
We therefore conclude that the planes met after 3.5 hours.
Hope this helps!
. Perimeter of regular polygons, however, is a required topic. Area (regular polygon) Regular polygons have all sides of equal length. a = apothem p = perimeter


Take HJ = a, GH = b and GJ = c
put the value of a from equation 1 in equation 2
now, put the value of a and c in equation 3
Now, we need to find HJ (a)
