Answer:
5.14 km
Step-by-step explanation:
A semicircle is 1/2 of a circle so the perimeter is just 1/2 of the circumference
C = 2 * pi r for a circle so for a semicircle
1/2* 2* pi *r
pi*r
3.14 * 1
3.14
If we want to include the piece that closes the semicircle, we need to add the diameter
d = 2r = 2(1) = 2
2+3.14 = 5.14
Answer: The costs are 8.4% of the total revenue.
The stadium is going to make $750,000 for the naming rights of the stadium. The cost to the stadium is on $63,000.
To find the percent, we have to divide the two values and multiply by 100.
63000 / 750000 x 100 = 8.4%
A = bh
b = 16
h = 3
A = 16*3
A = 48 square centimenters
Answer:
0.0089 cm
Step-by-step explanation:

Answer: 15 grams
If he had 100 grams of candy bar, then 30% of that is 30 grams (since 30/100 = 30%). Cut this in half and we end up with 30/2 = 15.
Another way to find the answer is to multiply 50 and 0.30 which is the decimal form of 30%. So we have 50*0.30 = 15 which is the same answer.
