The area of a circle with a radius of 7 cm is: 153.9 cm2
Area of the rectangle = base*height and measured in square yards
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
AnswerYou do the radius x radius then multipy it by pi.Say my radius is 7 . 7 x 7 = 4949 x 3.14 (3.14 is pi.)
The radius is 7 meters.
Area = pi*10.32 = 333.2915646 square yards
what is 9yds =
Area = π × radius² → radius = √(Area / π) Circumference = 2 × π × radius = 2 × π × √(Area / π) = 2 × √(Area × π) 1 acre = 4840 sq yds → circumference = 2 × √(1.5 × 4840 sq yds × π) ≈ 302 yds.
Formula for finding circumference is Pi (3.14) X diameter, so 12 yds times 3.14 = yds. Formula for area is Pi (3.14) x radius (1/2 the diameter=6) squared. So the radius squared is 6 X 6 = 36, X 3.14. You can do the math! Area will be in square yds.
The area of a regular pentagon with a radius of 7 is 10.1716. If the radius was 5, the area would be 7.26543.
The surface area of a sphere with a radius of 7 is about 615.8 units2
Total surface area = (2*pi*62)+(pi*12*10) = 603.186 square yards rounded to 3 decimal places
pi x area of base x length. My guess is that the "7" is a prompt to use 22/7 for pi, so volume =7 x pi x 12 cu ft = 7 x 22/7 x 1 / 33 cu yds =22/27 cu yds
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
The area of a circle with a radius of 7 cm is: 153.9 cm2
Area equals pi times the radius squared, so: A=3.14x52 A=3.14x25 A=78.5 square yds.
