Answer: Area= 459.73cm^2
Step-by-step explanation: Circumference of a circle is 2πr
76=2×3.14×r
r= 76÷(6×3.14)
r=12.10
Area of a circle= πr^2
Area= 3.14×(12.10)^2
Area= 456.73cm^2
Answer: 21.994 cm²
Step-by-step explanation:
Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.
Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142
Now area of the bigger circle = 3.142 x 3²
= 3.142 x 9
= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2
= 6.284 cm².
Therefore are of the shaded region = 28.278 - 6.284
= 21.994 cm²
The breadth of rectangle is 14 cm
The perimeter of rectangle is 65 cm
<em><u>Solution:</u></em>
Given that,
Area of rectangle = 259 square centimeter
Length of rectangle = 18.5 cm
<em><u>The area of rectangle is given by formula:</u></em>
<h3><u>Find the breadth:</u></h3>
Substitute the given values in above formula:
Thus breadth is 14 cm
<h3><u>Find the perimeter:</u></h3>
The perimeter of rectangle is given by formula:
Substitute the given values in above formula:
Thus perimeter of rectangle is 65 cm
Answer: 6.25 miles
Step-by-step explanation:
Convert the 15 minutes to 1/4 hr or .25
now multiply 25*.25=6.25 miles
Answer:
the next two terms are 17, 20
Step-by-step explanation:
add 3 to each term
Example
