Answer:No, the sum of the parallelogram's four angles must be equal to 360

Step-by-step explanation:

All four of a parallelogram's angles must add up to 360. Here, the angles only add up to 45 * 2 + 75 * 2 = 240 degrees.

Also, two adjacent angles must add up to 180. Here, the two adjacent angles 45 and 75 only add up to 120 degrees.

The formula for the surface area of the cylinder

= 2πr(r + h)

Height = 10 yd

I need help on this one!!! Please helppppppp!
tatuchka [14]

Answer:

Step-by-step explanation:

For pi i use the estimate 3.14

First find the radius of the sphere using the formula circumference= pi * diameter 273=3.14d

then divide both sides of the equation by d to get the diameter, which is about 86.94.

To get the radius, divide the diameter by 2, which equals 43.47.

Use the formula 4\pi r^2 to get the surface area, which is, rounded to the nearest number, is 23,734 feet
