Answer:
Area=11,309.73
Step-by-step explanation:
area of a circle is πr^2 so half of the diameter is the radius so it's 60.
pi x 60^2= 11,309.73
I guess B. That statement is grammatically incorrect.
Answer:
- Length and width of rectangle is 24 and 8 inches
Step-by-step explanation:
<u>Given:</u>
- Length of rectangle is three times the width
- Perimeter of rectangle is 64 Inches
<u>To Find:</u>
<u>Solution:</u>
Let's assume Width of rectangle x inches and length be 3x inches. To calculate the dimensions of The rectangle we will use the formula of Perimeter of rectangle:
Perimeter of rectangle = 2(L + B)
→ 64 = 2(3x + x)
→ 64 = 2(4x)
→ 64/2 = 4x
→ 32 = 4x
→ 32/4 = x
→ 8 = x
Hence,
- Length of the rectangle = 3x = 3(8) = 24 inches
- Width of the rectangle = x = 8 inches
Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63
Answer:
10 ft/s
Step-by-step explanation:
If Kristina is running at a rate of 11 ft/s and on a circular track with radius of 44 ft, then her angular speed is:
And so is Darrin's angular speed. That means his rate is
