The area of the circle is 113.04 cm²
<u>Step-by-step explanation:</u>
The given information are,
- The diameter of the circle = 12 cm
- The diameter must be converted into radius.
Radius = diameter / 2
Radius = 12/2 = 6 cm
Now, the formula for area of the circle is given by πr²
where,
- r is the radius of the circle.
- π has the default value 3.14
<u>To calculate the area of circle :</u>
Substitute r=6 and π=3.14,
Area of the circle = (3.14) × (6²)
⇒ 3.14 × 36
⇒ 113.04 cm²
The area of the circle is 113.04 cm²
Equation of circumference is C=2pi times radius
So radius being 32 and pi being 3.14
You would do
2x3.14x32
= 200.96

Step-by-step explanation:
2/5×1/4×3/8 is 6/160
Answer:
4 t - 7 = 2 t+ 13 is the required equation.
The number of race medals Tara has is t = 20 medals.
Step-by-step explanation:
Let the number of medals Tara has = t medals
So, the number of medal Anita has = 4( Medals of Tara) - 7
= 4t - 7
And the number of medals Gary has = 2 times (Medals of Tara) + 13
= 2(t) + 13 = 2t + 13
Now, Annita and Gary has same number of medals.
⇒ 4t - 7 = 2t+ 13
or, 4t - 2t = 7 + 13
⇒ 2t = 20
⇒ t = 20/2 = 10
or t = 10
Hence, the number of race medals Tara has is t = 20 medals
Answer:
660 square feet
Step-by-step explanation:
1 chain = 66 feet
Length ( l ) = 66 feet
Breadth ( b ) = 10 feet
To find :
The area of a cricket pitch in square feet = ?
The area of a cricket pitch in square feet will be in the shape of rectangle.
Formula : -
Area of a rectangle = lb
Area of a rectangle
= 66 x 10
= 660 square feet
Therefore,
660 square feet is the area of a cricket pitch.
