Answer:
49π
Step-by-step explanation:
area of circle = πr^2
<em>Handy Tip: cherry pies delicious; apple pies are(R) too(2)! so C = πd and A = πr^2</em>
diameter = 14 cm
radius = 14/2 = 7cm
area of circle = π(7)^2
area of circle = 49π
Hope that helps!
Answer:
Fossils: number one
Continental Shapes: number three
Seafloor Spreading: number two
Mammals: If the number of Mammal exhibits is 25 and there are 75 total exhibits, the Mammal exhibits are 1/3 of the total exhibits at this Zoo. The ratio for 1/3 is 1:3, which is 25:75 in most complex form. That's 33.3 as a percentage, or 33.3%.
Reptiles: If the number of Reptile exhibits is 15 and there are 75 total exhibits, the reptile exhibits are 1/5 of the total exhibits here. The ratio for 1/5 is 1:5, which is 15:75 fully written out. This as a percentage is 20%.
