The diameter of a circle is 11 m. Find its area to the nearest tenth.
1 answer:
Answer:
95.0 m²
Step-by-step explanation:
The formula for the area of a circle of radius r is A = πr².
Here the diameter is given and is 11 m; therefore the radius is r = (11/2) m.
Thus, the area of this circle is
A = πr² = π(11/2 m)² = π(121/4) m², or approx. 95.0 m²

Step-by-step explanation:
Sector area= theta/360 x πr^2
Radius= 24/2= 12
Sector area= 120/360 x π(12)^2
Final answer :
Sector area = 48π
