Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
Answer:r=20 cubic inches
Step-by-step explanation: Looking at this question critically and solving it mathematically, then we are going to say the volume of cylinder is πr^2h
V=15072 cubic inches r=? H=12cubic inches
15072cubic inches=3.14×r^2×12cubic inches
15072cubic inches=37.68 cubic incher^2
r^=400
We are going to take square of both sides, and our answer will now be
r=20 cubic inches
Answer:
see explanation
Step-by-step explanation:
(a)
The common difference (d) in an arithmetic sequence is
d = - = 24 - 2 = 22
To obtain the next term in the sequence add 22 to the previous term
= 46 + 22 = 68
= 68 + 22 = 90
= 90 + 22 = 112
--------------------------------------------------
(b)
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
here a = 2 and d = 22, hence
= 2 + 22(n - 1) = 2 + 22n - 22 = 22n - 20 ← n th term formula
---------------------------------------------------------------------
(c)
Using the n th term formula
= (22 × 35) - 20 = 770 - 20 = 750
Answer:
P = 46.6 feet
Step-by-step explanation:
P = 2L + 2W, where P is perimeter, L is length, and W is width.
2 x Length (L) = 2 x 15.5 feet = 31 feet;
2 x Width (W) = 2 x 7.8 feet = 15.6 feet.
Add both length and width together:
2L + 2W = 30.1 + 15.6 = 46.6 feet.
The perimeter (P) = 46.6 feet.
