Answer:
90°
Step-by-step explanation:
since PQ is the diameter of the circle, m <em>L</em><em> </em>PRQ = ½ × 180° = 90°.
so, as a supplementary to <em>L</em><em> </em>PRQ, the value of angle QRS = 180 - m <em>L</em><em> </em>PRQ = 180-90 =90°
Answer:
<u>6b - 4a + 22 units</u>
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(3b - 4a + 5 + 6 + 2a)
= 2(3b - 2a + 11)
= <u>6b - 4a + 22 units</u>
Answer:
67.029 cm ³
Step-by-step explanation:
Volume of cone = ¹/³ πr²h
π= 3.142 , r = diameter /2 so r =2cm , height (h) = 16cm
so V = ¹/³ π x (4) x 16
V = 62.029cm³
