Answer:

126∏

Step-by-step explanation:

area = 2 * area of the circle + area of the rectangular surface

area = 2 * r² * ∏ + 2 * r * ∏ * h

area = (2 * r² + 2 * r * h) * ∏

area = (2 * 7² + 2 * 7 * 2) * ∏

Find the measure of the missing angles. WILL GIVE BRAINLIEST

Ivahew [28]

D = 90
This is because any line is equal to 180 degrees, we see that d is situated on a line that continues into another angle, the other angle is 90 degrees, so we minus 90 from 180, to get 90.

E = 99
E is situated on a line with the other angle F, F = 81 (see below) so we minus 81 from 180

F = 81
F is situated on a line, we minus it from the other angle situated on the same line, so we minus 99 from 180to get 81

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
