24 + 12 / 6 x 3
=36 / 6 x 3
= 6 x 3
= 18
Answer:
2
Step-by-step explanation:
Diameter = 14
Radius = 7 inches
Volume = (4/3)×3.14×7³ = 1436.026667 inches³
1436.026667 ÷ 693 = 2.072187552
Answer:
circumference of circle = 2π×r
here r = 7
so 2 ×22÷7 × 7
= 2×22
= 44
therefore the circumference is 44 inches
The polygon have 59 sides.
Solution:
Sum of the measure of interior angle of the polygon = 10260°
Interior angle theorem of polygon,
<em>The sum of measure of interior angles of a polygon is (n – 2) × 180°.</em>
By this theorem,
(n – 2) × 180° = 10260°
Divide by 180° on both sides.
Add 2 on both sides, we get
n – 2 + 2 = 57 + 2
n = 59
Hence the polygon have 59 sides.
