Answer:
50.24 ft^2
Step-by-step explanation:
The radius of the circle in which the lawn sprinkler sprays water is 4 feet.
The formula to find the area of a circle is
, where r = radius and π, in this case, is 3.14.
- 3.14 × 4^2
- 3.14 × 16
- 50.24 ft^2
Therefore, the answer is 50.24 ft².
Step-by-step explanation:
a=8cm
b=15cm
c=17cm
s=a+b+c/2
=8+15+17/2
=40/2
=20
Using heron's formula,
ar. of triangle= √s(s-a)(s-b)(s-c)
=√20(20-8)(20-15)(20-17)
=√20×12×5×3
=√2×2×5×2×2×3×5×3
=2×2×3×5
=60cm²
On side 17cm,
Ar. of triangle=1/2×b×h
60=1/2×17×h
∴h=60×2/17
=7.05 cm
