We know that
[area of a circle]=pi*r²
r=10 in
[area of a circle]=pi*10²-----> 100*pi in²
if 360° (full circle) has an area of------------------> 100*pi in²
45°-------------------------------> X
X=45*100*pi/360-----> x=12.5*pi in²
the answer is
the option B) 12.5*pi in²
Answer:
Option c - 67.5
Step-by-step explanation:
Base= 15
Height = 9
Area= 1/2 x b h = 1/2 x 9 x 15 = 67.5 feet
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We can find 'a' through Pythagoras theorem.</u>
- => 8² = 3² + a²
- => 64 = 9 + a²
- => a² = 55
- => a = √55
- => a = 7.416 = 7.4

Answer:
42 sq feet
Step-by-step explanation:
w = 26 ÷ 2 - 7 = 6 ft
A = lw = 6 × 7 = 42
