Answer:
Option B is correct.
Step-by-step explanation:
<h3>The length of legs of isosceles right triangle is 8.5 cm</h3>
<em><u>Solution:</u></em>
Given is a isosceles triangle
hypotenuse = 12 cm
In an isosceles right triangle, the legs have equal lengths
Let these sides be each "a" cm
By pythogoras theorem,
Thus the length of leg of isosceles right triangle is 8.5 cm
So 7/4 decreased by a number -x is 2 =2 or
7/4-x=2
add x to both sides
7/4=2+x
subtract 2 from both sides
2=8/4
7/4-8/4=-1/4
x=-1/4
Answer:
Volume is 718 cm^3
Step-by-step explanation:
We need to get the radius of cylinder A
From the base area,
we have that;
A = pi * r^2
18 = 3.142 * r^2
r^2 = 18/3.142
r^2 = 5.73
r= √5.73
r = 2.39
If two shapes are similar, we have the ratio of their corresponding sides equal;
Thus;
2.39/5 = x/10
x = (10 * 2.39)/5
x = 4.78 cm
To get the volume, we use the formula
V = pi * r^2 * h
V = 3.142 * 4.78^2 * 10
V = 717.8 cm^3
This is approximately 718 cm^3
