Step-by-step explanation:
Surface area of cylinder = 2πrh + 2πr^2
SA for cylinder A = 2π x 2 x 2 + 2π x (2)^2 = 8π + 8π = 16π
SA for cylinder B = 2π x 2 x 4 + 2π x (2)^2 = 16π + 8π = 24π
2(4)2 - 10 / 2 = 8(2) - 10 / 2 = 16 - 5 = 11 (FINAL ANSWER)
Answer:
x = 8 cm
Step-by-step explanation:
Given that,
In a square PQRS, PQ = 2x +3 cm and QR = 3x – 5 cm.
We need to find the value of x.
In a square, all the sides are equal. So,
PQ = QR
2x +3 = 3x – 5
3+5 = 3x - 2x
x = 8
So, the value of x is equal to 8 cm.
Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have two standard form equations which we will get a slope and a y-intercept from. We will convert each to slope intercept form to get the information. We will then write a new slope-intercept equation and convert to standard form.
3x-5y=7 has the same slope as the line. Let's convert.


The slope is
.
2y-9x=8 has the same y-intercept as the line. Let's convert.


The y-intercept is 4.
We take
and b=4 and substitute into y=mx+b.

We now convert to standard form.

For standard form we need the coefficients of x and y to be not zero or fractions. We need integers but the coefficient of x cannot be negative. So we multiply the entire equation by -5 to clear the denominators.
