Answer:
Area of Circle = 346.5 cm².
Area of square = 272.25 cm ² .
Step-by-step explanation:
So , 2πR = 66
2 × 22 / 7 × R = 66
R comes out is 21/2 cm .
Area of Circle = 22/7 × 21/2 × 21/2 = 33×21/2
= 693 / 2 = 346.5 cm².
If bent into the shape of a square ;
4 a = 66
a = 33/2 . ( Side of a square )
Area of square = a ² = 33×33/4 = 1089/4
= 272.25 cm ² .
Answer:
Step-by-step explanation:
<h3>Question 1</h3>
V and W are midpoints of RU and ST ⇒ VW is a midsegment
VW = 1/2(RS + UT) ⇒ RS = 2*VW - UT
<u>Substitute values:</u>
- 2x + 15 = 2(2x + 5) - (6x - 37)
- 2x + 15 = 4x + 10 - 6x + 37
- 2x + 15 = -2x + 47
- 2x + 2x = 37 - 15
- 4x = 22
- x = 5.5
RS = 2x + 15 = 2(5.5) + 15 = 11 + 15 = 26
Question 2
- Trapezoid given with congruent sides, JM = KL
- Angle J and K are congruent, both are (7x + 2)
- Angles M and L are congruent, both are (2x - 14)
<u>J and M are supplementary, so sum to 180°</u>
- 7x + 2 + 25x - 14 = 180
- 32x = 192
- x = 192/32
- x = 6
