We know that
<span>diameter of the base of a cylindrical can= 4 in----------> r=2 in
h=6.5 in
</span>[surface area]=2*[pi*r²]+[2*pi*r*h]
then
[surface area]=2*[pi*2²]+[2*pi*2*6.5]=[ 25.13 ]+[ 81.68 ]=106.81 in²
the answer is 106.8 in²
Answer:
a. You have chosen 20 ft for the perimeter.
b. l = 10 - w
Step-by-step explanation:
b. You are told to solve the formula for l. Presumably, you are to put your number in place of P.
20 = 2l + 2w
10 = l + w . . . . . divide by 2 (because we can. It simplifies the expression.)
To solve for l, we subtract w from both sides of the equation.
10 - w = l + w - w
10 - w = l . . . . . an expression for the length of the cage in terms of w
x intercept = -5
C or #3 will be your answer
Answer:
Let the number of pages be y and the number of chapters be x, then y = 24 + 12x + 48 = 12x + 72
y = 12x + 72
If the book has 25 chapters, the number of pages will be y = 12(25) + 72 = 300 + 72 = 37 pages.

Answer:
3,600
Step-by-step explanation:
Volume of a triangular pyramid is V=1/3 Base times height.
B=1/2bh
B=1/2 (24)(30)
B=360
The height is 30 so we now multiply 30 times 360 which is 10,800.
Last, we multiply 10,800 times 1/3 which is <u>3,600.</u>
