Given that:
Volume of cylinder, V= 87.92 cm³
Radius, r= 2 cm
π=3.14
Formula for volume of cylinder:
V=πr²h
Put values in the formula.
87.92=(3.14)(2)²h
87.92=(3.14)(4)h
87.92=12.56h
Divide both sides by 12.56
7=h
or
h=7 cm
Answer: Height of Cylinder is 7 cm.
Answer:
107%
Step-by-step explanation:
Emma spending 7% more on the sweater than the shoes can be represented by x + 7%, where x is the price of the shoes.
The shoes are worth 100%, or one whole, because you can't buy half a shoe or more than one whole shoe, etc.
So to find how much more the sweater is, add 100% to 7%, or how much more the sweater is.
100% + 7% = 107%
The cost of the sweater is 107% of the cost of the shoes.
The poster is a rectangle.
P = 2 L + 2 W
where L is the length and W is the width of a rectangle.
L = W + 2 1/2 = W + 2.5
103 = 2 ( W + 2.5 ) + 2 W
103 = 2 W + 5 + 2 W
103 = 4 W + 5
4 W = 103 - 5
4 W = 98
W = 98 : 4
W = 24.5 in
L = 24.5 + 2.5
L = 27 in
Answer:
The poster is 27 inches long and 24.5 inches wide.
Answer:
-4 and 2
Step-by-step explanation:
the graph intersects the x-axis only at the points (-4,0) and (2,0) so the only zeroes of the graph are going to be -2 and 2
