Answer:
Given - Diameter of circle = 14 in
To find - Area of circle
Solution -
Diameter= 2 × Radius
14 = 2 × R
14/2 = R
7 = R
Area of circle= π r^²
22/7 × 7 × 7
22 × 7
154
Answer:
90 degrees
Step-by-step explanation:
angle b is 180-90-56=34 degrees
that means angle c is also 34 degrees.
56+34=90, thus angle BCE is also 90 degrees
Answer:
262.6/300% for the first 3 test if you were to add another test it would be 400% total and you need 360% of test grades to have an average of 90% and so 360 - 262.6 = 97.4%
Step-by-step explanation:
51/2x-7=62
- Multiply both sides by 2x-7
×(2x-7) = 62(2x-7)
2. Switch sides
62(2x-7) = 51
3. Divide each side by 62
= 
4. Simplify
2x-7 = 51/62
5. Add 7 on both sides
2x-7+7 = (51/62)+7
6. Simplify
2x = 485/62
7. Divide both sides by 2
2x/2= 485/62/2
x= 485/124
Quadrilateral, square, four sided, 90 degrees, also forms a diamond
