E^2=0.36 take the square root of both sides
e=±0.6
Answer:
total surface area of cone is πr (r+l)
22/7 x 3 (3+4)
22/7*3 (7)
22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket)
hence,
TSA of cone = 66pi
The square would be 100.
The semicircle you will use the formula πr^2/2.
That would mean you would take the 3.14x5^2/2.
(3.14x5x5)/2
(3.14x25)/2
78.5/2
=39.25
So the total area would be 139.25
9/14 the anwser its really easy but i understand
Answer:
P = 16x + 8
Step-by-step explanation:
Perimeter of a rectangle
= 2(L + W)
Given
L = 5x + 4 and
W = 3x
Therefore
Perimeter = 2(5x + 4 + 3x)
Rearrange the expression
P = 2(5x + 3x + 4)
P = 2(8x + 4)
Now expand the bracket
P = 2 x 8x + 2 x 4
P = 16x + 8
