Answer:
49π or 153.938 mm²
Step-by-step explanation:
Area of a Circle Formula: A = πr²
Since we are given radius <em>r</em>, simply plug it into the formula:
A = π(7)²
A = 49π
A = 153.938
Answer:
Check below
Step-by-step explanation:
1) These metric volume units can be easily converted by dividing or multiplying by 10 and its multiple. Like this: each step up on the ladder multiply by 10. Each step down divide by 10
.
2) When it comes to area, the "ladder scheme" remains valid but now we'll multiply or divide by
Bear in mind these useful relations:
Answer:
<h3> in square feet</h3>
Step-by-step explanation:
Area of anything is<u> allways </u>reported <u>in square units</u>. Usually that is square of given unit because it's the simplest way:
R = 50 ft
A = πR² = π•(50 ft)² = π • 50 ft • 50 ft = 2500π ft² ≈ 7854 ft²
{Of course you can re-calculate the units, ex.:
3 feet = 1 yard so 50 ft = 50/3 yd then
A = πR² = π•(50/3 yd)² = π • 50/3 yd • 50/3 yd = 2500/9 π yd² ≈ 872.7 yd² }
Let's solve for p when the two expressions are equal.
Answer:
cost of one drink: $1.70
Step-by-step explanation:
P = price of pizza
L = Price of each large drink
Gift certificate discount =$ 7
Net paid= $12.10
P +3L -7 = 12.10
14 +3L -7 =12.10
7+3L =12.10
3L = 12.10 -7 = 5.10
L = $1.70 for each large drink
hopefully this helped :3
