99º, because the sum of all 4 of the interior angles of the parallelogram must be 360º. We know that if one angle measures 81º the other angle on the opposite side must measure 81º.. so 81+81=162
360-162=198
198 - 2(number of remaining angles) = 99º
Answer:
Step-by-step explanation:
Given: The radius is 6 cm
To find the area + circumference we need to use 2 formulas:
Area: pi* radius^2
Circumference: 2*pi*r
First we can do the area
I will use "pi" for pi instead of 3.14
pi * 6^2
= 36 pi
The area is 36 pi
Next, circumference
2 * pi *r
2*pi*6
= 12 pi
So the area is 36 pi, and the circumference is 12 pi
Answer:
answer is 746.
have a nice day and do good in math
7/10 divided by 3/8
7/10 x 8/3 = 56/30
56/30 divided by 2 = 28/15 = 1 13/15
The answer is B. 1 13/15
