Question

Find the area of the semicircle with a Dynamiter of 10. Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.

Answer 1

Answer:

answer is 39.25

Step-by-step explanation:

• $\pi \: r {}^{2} \div 2$
• (3.14×25)÷2
• 1.57×25
• 39.25

diameter is 10 so radius is 5

area of circle = 2× area of semi circle

Answer 2

Answer:

25π/2

Step-by-step explanation:

Given, diameter = 10

radius = 10/2 = 5

Area of circle = π *r*r

Area of semi circle = (π*r*r)/2

= (π*5*5)/2

= 25π/2
