Answer:
It looks like 10r + 10.
Step-by-step explanation:
-2r + 12r = 10r
-5a + 5a = 0
+ 10 = 10
The radius of the circle is 5.30 cm.
<h3>What is a radius?</h3>
A radius is a line that extends from the center of a circle to any point of the circumference.
To calculate the length of the radius of the circle, we use the formula below.
Formula:
- A = πr²......... Equation 1
Make r the subject of the equation
- r = √(A/π).................. Equation 2
Where:
- A = Area of the circle
- r = Radius of the circle
- π = Pie
From the question,
Given:
Substitute these values into equation 2
- r = √(88.44/(22/7))
- r = √(88.44×7/22)
- r = √(28.14)
- r = 5.30 cm
Hence, the radius of the circle is 5.30 cm.

Answer:
Step-by-step explanation:
15) tanA = 6.8/3.0
16) tanR = 9/24
17) tanB = 16/17
18) BC = 10tan40
19) PQ = 38/tan75
20 BC seems to be missing some of its length number I will call it 14
redo if that is incorrect.
∠A = arctan(14 / 14.5)
∠C = arctan(14.5 / 14)
Baking, cooking, reading, playing games, watching movies, cleaning up can be nice, gardening
Each time there are 6 possible outcomes.
If you roll four times, the number of possible outcomes would be 6^4, or 1296.
Final answer: 1296 configurations.
