Answer:
39 units²
Step-by-step explanation:
the perimeter of triangle =
7+6+9.22 = 22.22 cm
=> the radius oh the circle =
r = c/2π = 22.22/ 2×3.14
= 3.54
so, the area of the circle = π.r²
= 3.14 ×(3.54)²
= 3.14 × 12.53
= 39.34 => 39 units²
Answer:
The terms are - 1, 7 and 15.
Step-by-step explanation:
Let the terms be a-d, a and a+d
ATQ, a-d+a+a+d=21, a=7. a+d-(a+(a-d))=9. d=8. The terms are - 1, 7 and 15.
